1. Introduction
Providers of Internet content and other services may wish to
customize those services based on the geographic location of the user
of the service. This is often done using the source IP address used
to contact the service, which may not point to a user, user; see [RFC6269], Section 14
of [RFC6269] in particular. Also, administrators of infrastructure
and other services might wish to publish the locale of said
infrastructure or services. infrastructure and other services might
wish to publish the locale of their services. [RFC8805] defines
geofeed, a syntax to associate geographic locales with IP addresses,
but it does not specify how to find the relevant geofeed data given
an IP address.
This document specifies how to augment the Routing Policy
Specification Language (RPSL) [RFC2725] inetnum: class to refer
specifically to geofeed data files and how to prudently use them. In
all places inetnum: is used, inet6num: should also be assumed
[RFC4012].
The reader may find [INETNUM] and [INET6NUM] informative, and
certainly more verbose, descriptions of the inetnum: database
classes.
An optional utterly awesome but slightly complex means for
authenticating geofeed data is also defined in Section 5.
This document obsoletes [RFC9092]. Changes from [RFC9092] include
the following:
* RIPE has implemented the geofeed: attribute.
* Allow, This document allows, but discourage, discourages, an inetnum: to have both a
geofeed remarks: attribute and a geofeed: attribute.
* Rewrite The Authentication Section 5 section (Section 5) has been rewritten to be
more formal.
* Geofeed file files are only UTF-8 CSV.
* Stress This document stresses that authenticating geofeed data is
optional.
* IP Address Delegation extensions must not use "inherit".
* If geofeed data are present, ignore geographic location hints in other data.
data should be ignored.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
2. Geofeed Files
Geofeed files are described in [RFC8805]. They provide a facility
for an IP address resource "owner" to associate those IP addresses to
geographic locales.
Per [RFC8805], geofeed files consist of CSVs (Comma Separated Values) comma-separated values (CSV)
in UTF-8 text format; format, not HTML, richtext, or other formats.
Content providers and other parties who wish to locate an IP address
to a geographic locale need to find the relevant geofeed data. In
Section 3, this document specifies how to find the relevant geofeed
[RFC8805] file given an IP address.
Geofeed data for large providers with significant horizontal scale
and high granularity can be quite large. The size of a file can be
even larger if an unsigned geofeed file combines data for many
prefixes, if dual IPv4/IPv6 spaces are represented, etc.
Geofeed data do have privacy considerations (see Section 7); this
process makes bulk access to those data easier.
This document also suggests an optional signature to strongly
authenticate the data in the geofeed files.
3. inetnum: Class
The original RPSL specifications starting with [RIPE81], [RIPE181],
and a trail of subsequent documents were written by the RIPE
community. The IETF standardized RPSL in [RFC2622] and [RFC4012].
Since then, it has been modified and extensively enhanced in the
Regional Internet Registry (RIR) community, mostly by RIPE [RIPE-DB].
At the time of publishing this document, change control of the RPSL
effectively lies in the operator community.
The inetnum: database class is specified by the RPSL, and as well as
Routing Policy System Security [RFC2725] and [RFC4012] RPSLng [RFC4012], which
are used by the Regional Internet Registries (RIRs), specify the inetnum: database class. (RIRs). Each of these
objects describes an IP address range and its attributes. The
inetnum: objects form a hierarchy ordered on the address space.
Ideally, the RPSL would be augmented to define a new RPSL geofeed:
attribute in the inetnum: class. Absent implementation of the
geofeed: attribute in a particular RIR database, this document
defines the syntax of a Geofeed remarks: attribute, which contains an
HTTPS URL of a geofeed file. The format of the inetnum: geofeed
remarks: attribute MUST be as in this example, "remarks: Geofeed ",
where the token "Geofeed " MUST be case sensitive, followed by a URL
that will vary, but it MUST refer only to a single geofeed [RFC8805]
file.
inetnum: 192.0.2.0/24 # example
remarks: Geofeed https://example.com/geofeed
While we leave global agreement of RPSL modification to the relevant
parties, we specify that a proper geofeed: attribute in the inetnum:
class MUST be "geofeed:" and MUST be followed by a single URL that
will vary, but it MUST refer only to a single geofeed [RFC8805] file.
inetnum: 192.0.2.0/24 # example
geofeed: https://example.com/geofeed
The URL uses HTTPS, so the WebPKI provides authentication, integrity,
and confidentiality for the fetched geofeed file. However, the
WebPKI can not cannot provide authentication of IP address space assignment.
In contrast, the RPKI (see [RFC6481]) can be used to authenticate IP
space assignment; see optional authentication in Section 5.
Until all producers of inetnum: objects, i.e., the RIRs, state that
they have migrated to supporting a geofeed: attribute, consumers
looking at inetnum: objects to find geofeed URLs MUST be able to
consume both the remarks: and geofeed: forms.
The migration not only implies that the RIRs support the geofeed:
attribute, but that all registrants have migrated any inetnum:
objects from remarks: to geofeed: attributes.
Any particular inetnum: object SHOULD have, at most, one geofeed
reference, whether a remarks: or a proper geofeed: attribute when it
is implemented. As the remarks: form can not cannot be formally checked by
the RIR, this can not cannot be formally enforced. A geofeed: attribute is
preferred, of course, if the RIR supports it. If there is more than
one type of attribute in the intetnum: object, the geofeed: attribute
MUST be used.
For inetnum:s inetnum: objects covering the same address range, a signed
geofeed file MUST be preferred over an unsigned file. If none are
signed, or more than one is signed, the (signed) inetnum: with the
most recent last-
modified: last-modified: attribute MUST be preferred.
If a geofeed file describes multiple disjoint ranges of IP address
space, there are likely to be geofeed references from multiple
inetnum: objects. Files with geofeed references from multiple
inetnum: objects are not compatible with the signing procedure in
Section 5.
An unsigned, and only an unsigned, geofeed file MAY be referenced by
multiple inetnum:s inetnum: objects and MAY contain prefixes from more than one
registry.
When fetching, the most specific inetnum: object with a geofeed
reference MUST be used.
It is significant that geofeed data may have finer granularity than
the inetnum: that refers to them. For example, an INETNUM object for
an address range P could refer to a geofeed file in which P has been
subdivided into one or more longer prefixes.
4. Fetching Geofeed Data
This document is to provides a guideline for how interested parties should
fetch and read geofeed files.
Historically, before [RFC9092], this was done in varied ways, at the
discretion of the implementer, implementor, often without consistent
authentication, where data were mostly imported from email without
formal authorisation authorization or validation.
To minimize the load on RIRs' WHOIS [RFC3912] services, the RIR's FTP
[RFC0959] services SHOULD be used for large-scale access to gather
inetnum:s
inetnum: objects with geofeed references. This uses efficient bulk
access instead of fetching via brute-force search through the IP
space.
When reading data from an unsigned geofeed file, one MUST ignore data
outside the referring inetnum: object's address range. This is to
avoid importing data about ranges not under the control of the
operator. Note that signed files MUST only contain prefixes within
the referring inetnum:'s range as mandated in Section 5.
If geofeed files are fetched, other location information from the
inetnum: MUST be ignored.
Given an address range of interest, the most specific inetnum: object
with a geofeed reference MUST be used to fetch the geofeed file. For
example, if the fetching party finds the following inetnum: objects:
inetnum: 192.0.0.0/22 # example
remarks: Geofeed https://example.com/geofeed_1
inetnum: 192.0.2.0/24 # example
remarks: Geofeed https://example.com/geofeed_2
An application looking for geofeed data for 192.0.2.0/29, 192.0.2.0/29 MUST ignore
data in geofeed_1 because 192.0.2.0/29 is within the more specific
192.0.2.0/24 inetnum: covering that address range and that inetnum:
does have a geofeed reference.
Hints in inetnum:s inetnum: objects such as country:, geoloc:, etc. tend to be
administrative, and not deployment specific. Consider large,
possibly global, providers with headquarters very far from most of
their deployments. Therefore, if geofeed data are specified, either
as a geofeed: attribute or in a geofeed remarks: attribute, other
geographic hints such as country:, geoloc:, DNS geoloc RRsets, etc.,
for that address range MUST be ignored.
There is open-source code to traverse the RPSL data across all of the
RIRs, collect all geofeed references, and process them
[GEOFEED-FINDER]. It implements the steps above and of all the
Operational Considerations described in Section 6, including caching.
It produces a single geofeed file, merging all the geofeed files
found. This open-source code can be run daily by a cronjob, cron job, and the
output file can be directly used.
RIRs are converging on RDAP support Registration Data Access Protocol (RDAP)
support, which includes geofeed data, data; see
[I-D.ietf-regext-rdap-geofeed]. [RDAP-GEOFEED]. This
SHOULD NOT be used for bulk retrieval of geofeed data.
5. Authenticating Geofeed Data (Optional)
The question arises whether a particular geofeed [RFC8805] data set
is valid, i.e., is authorized by the "owner" of the IP address space
and is authoritative in some sense. The inetnum: that points to the
geofeed [RFC8805] file provides some assurance. Unfortunately, the
RPSL in some repositories is weakly authenticated at best. An
approach where the RPSL was signed per [RFC7909] would be good,
except it would have to be deployed by all RPSL registries, and there
is a fair number of them.
The remainder of this section specifies an optional authenticator for
the geofeed data set that follows the Signed "Signed Object Template for the
Resource Public Key Infrastructure (RPKI) (RPKI)" [RFC6488].
A single optional authenticator MAY be appended to a geofeed
[RFC8805] file. It is a digest of the main body of the file signed
by the private key of the relevant RPKI certificate for a covering
address range. The following format bundles the relevant RPKI
certificate with a signature over the geofeed text.
The canonicalization procedure converts the data from their internal
character representation to the UTF-8 [RFC3629] character encoding,
and the <CRLF> sequence MUST be used to denote the end of each line
of text. A blank line is represented solely by the <CRLF> sequence.
For robustness, any non-printable characters MUST NOT be changed by
canonicalization. Trailing blank lines MUST NOT appear at the end of
the file. That is, the file must not end with multiple consecutive
<CRLF> sequences. Any end-of-file marker used by an operating system
is not considered to be part of the file content. When present, such
end-of-file markers MUST NOT be covered by the digital signature.
If the authenticator is not in the canonical form described above,
then,
then the authenticator is invalid.
Borrowing detached signatures from [RFC5485], after file
canonicalization, the Cryptographic Message Syntax (CMS) [RFC5652] is
used to create a detached DER-encoded signature that is then Base64
encoded with padding (as defined in Section 4 of [RFC4648]) and line
wrapped to 72 or fewer characters. The same digest algorithm MUST be
used for calculating the message digest of the content being signed,
which is the geofeed file, and for calculating the message digest on
the SignerInfo SignedAttributes [RFC8933]. The message digest
algorithm identifier MUST appear in both the CMS SignedData
DigestAlgorithmIdentifiers and the SignerInfo
DigestAlgorithmIdentifier [RFC5652]. The RPKI certificate covering
the geofeed inetnum: object's address range is included in the CMS
SignedData certificates field [RFC5652].
The address range of the signing certificate MUST cover all prefixes
in the signed geofeed file. If not, the authenticator is invalid.
The signing certificate MUST NOT include the Autonomous System
Identifier Delegation certificate extension [RFC3779]. If it is
present, the authenticator is invalid.
As with many other RPKI signed objects, the IP Address Delegation
certificate extension MUST NOT use the "inherit" capability defined
in Section 2.2.3.5 of [RFC3779]. If "inherit" is used, the
authenticator is invalid.
An IP Address Delegation extension using "inherit" would complicate
processing. The implementation would have to build the certification
path from the end-entity end entity to the trust anchor, then validate the path
from the trust anchor to the end-entity, end entity, and then the parameter would
have to be remembered when the validated public key was used to
validate a signature on a CMS object. Having to remember things from
certification path validation for use with CMS object processing
would be quite complex and error prone. And, error-prone. Additionally, the
certificates do not get that much bigger by repeating the
information.
An address range A "covers" address range B if the range of B is
identical to or a subset of A. "Address range" is used here because
inetnum: objects and RPKI certificates need not align on Classless
Inter-Domain Routing (CIDR) [RFC4632] prefix boundaries, while those
of the lines in a geofeed file do align.
The Certificate Certification Authority (CA) SHOULD sign only one geofeed file
with each generated private key and SHOULD generate a new key pair
for each new version of a perticular particular geofeed file. The CA MUST
generate a new End Entity end entity (EE) certificate for each signing of a
particular geofeed file. An associated EE certificate used in this
fashion is termed a "one-time-use" EE certificate (see Section 3 of
[RFC6487]).
Identifying the private key associated with the certificate and
getting the department that controls the private key (which might be
stored in a Hardware Security Module (HSM)) to generate the CMS
signature is left as an exercise for the implementor. On the other
hand, verifying the signature has no similar complexity; the
certificate, which is validated in the public RPKI, contains the
needed public key. The RPKI trust anchors for the RIRs are expected
to already be available to the party performing signature validation.
Validation of the CMS signature over the geofeed file involves:
1. Obtaining the signer's certificate from the CMS SignedData
CertificateSet [RFC5652]. The certificate SubjectKeyIdentifier
extension [RFC5280] MUST match the SubjectKeyIdentifier in the
CMS SignerInfo SignerIdentifier [RFC5652]. If the key
identifiers do not match, then validation MUST fail.
2. Validating the signer's certificate MUST ensure that it is part
of the current [RFC9286] manifest and that all resources are
covered by the RPKI certificate.
3. Constructing the certification path for the signer's certificate.
All of the needed certificates are expected to be readily
available in the RPKI repository. The certification path MUST be
valid according to the validation algorithm in [RFC5280] and the
additional checks specified in [RFC3779] associated with the IP
Address Delegation certificate extension and the Autonomous
System Identifier Delegation certificate extension. If
certification path validation is unsuccessful, then validation
MUST fail.
4. Validating the CMS SignedData as specified in [RFC5652] using the
public key from the validated signer's certificate. If the
signature validation is unsuccessful, then validation MUST fail.
5. Confirming that the eContentType object identifier (OID) is id-
ct-geofeedCSVwithCRLF (1.2.840.113549.1.9.16.1.47). This OID
MUST appear within both the eContentType in the encapContentInfo
object and within the ContentType signed attribute in the
signerInfo object (see [RFC6488]).
6. Verifying that the IP Address Delegation certificate extension
[RFC3779] covers all of the address ranges of the geofeed file.
If all of the address ranges are not covered, then validation
MUST fail.
All of the above steps MUST be successful to consider the geofeed
file signature as valid.
The authenticator MUST be hidden as a series of "#" comments at the
end of the geofeed file. The following simple example is
cryptographically incorrect:
# RPKI Signature: 192.0.2.0 - 192.0.2.255
# MIIGlwYJKoZIhvcNAQcCoIIGiDCCBoQCAQMxDTALBglghkgBZQMEAgEwDQYLKoZ
# IhvcNAQkQAS+gggSxMIIErTCCA5WgAwIBAgIUJ605QIPX8rW5m4Zwx3WyuW7hZu
...
# imwYkXpiMxw44EZqDjl36MiWsRDLdgoijBBcGbibwyAfGeR46k5raZCGvxG+4xa
# O8PDTxTfIYwAnBjRBKAqAZ7yX5xHfm58jUXsZJ7Ileq1S7G6Kk=
# End Signature: 192.0.2.0 - 192.0.2.255
A correct and full example is in Appendix A.
The CMS signature does not cover the signature lines.
The bracketing "# RPKI Signature:" and "# End Signature:" MUST be
present as shown in the example. The RPKI Signature's IP address
range MUST match that of the geofeed URL in the inetnum: that points
to the geofeed file.
6. Operational Considerations
To create the needed inetnum: objects, an operator wishing to
register the location of their geofeed file needs to coordinate with
their Regional Internet Registry (RIR) or National Internet Registry
(NIR) and/or any provider Local Internet Registry (LIR) that has
assigned address ranges to them. RIRs/NIRs provide means for
assignees to create and maintain inetnum: objects. They also provide
means of assigning or sub-assigning IP address resources and allowing
the assignee to create WHOIS data, including inetnum: objects,
thereby referring to geofeed files.
The geofeed files MUST be published via and fetched using HTTPS
[RFC9110].
When using data from a geofeed file, one MUST ignore data outside the
referring inetnum: object's inetnum: attribute address range.
If and only if the geofeed file is not signed per Section 5, then
multiple inetnum: objects MAY refer to the same geofeed file, and the
consumer MUST use only lines in the geofeed file where the prefix is
covered by the address range of the inetnum: object's URL it has
followed.
If the geofeed file is signed, and the signer's certificate changes,
the signature in the geofeed file MUST be updated.
It is good key hygiene to use a given key for only one purpose. To
dedicate a signing private key for signing a geofeed file, an RPKI
Certification Authority (CA) may issue a subordinate certificate
exclusively for the purpose shown in Appendix A.
Harvesting and publishing aggregated geofeed data outside of the RPSL
model should be avoided as it can have the effect that more specifics
from could lead to detailed data of one
aggregatee could undesirably affect affecting the less specifics detailed data of a
different aggregatee. Moreover, publishing aggregated geofeed data
prevents the reader of the data to perform from performing the checks described
in Section 4 and Section 5.
At the time of publishing this document, geolocation providers have
bulk WHOIS data access at all the RIRs. An anonymized version of
such data is openly available for all RIRs except ARIN, which
requires an authorization. However, for users without such
authorization, the same result can be achieved with extra RDAP
effort. There is open-source code to pass over such data across all
RIRs, collect all geofeed references, and process them
[GEOFEED-FINDER].
To prevent undue load on RPSL and geofeed servers, entity-fetching
geofeed data using these mechanisms MUST NOT do frequent real-time
lookups. Section 3.4 of [RFC8805] suggests use of the HTTP Expires
header [RFC7234] [RFC9111] to signal when geofeed data should be refetched. As
the data change very infrequently, in the absence of such an HTTP
Header signal, collectors SHOULD NOT fetch more frequently than
weekly. It would be polite not to fetch at magic times such as
midnight UTC, the first of the month, etc., because too many others
are likely to do the same.
7. Privacy Considerations
[RFC8805] geofeed data may reveal the approximate location of an IP
address, which might in turn reveal the approximate location of an
individual user. Unfortunately, [RFC8805] provides no privacy
guidance on avoiding or ameliorating possible damage due to this
exposure of the user. In publishing pointers to geofeed files as
described in this document, the operator should be aware of this
exposure in geofeed data and be cautious. All the privacy
considerations of Section 4 of [RFC8805] apply to this document.
Where [RFC8805] provided the ability to publish location data, this
document makes bulk access to those data readily available. This is
a goal, not an accident.
8. Implementation Status
At the time of publishing this document, the geofeed: attribute in
inetnum objects has been implemented in the RIPE and APNIC databases.
Registrants in databases which that do not yet support the geofeed:
attribute are using the remarks:, remarks: attribute, or equivalent, attribute. equivalent.
At the time of publishing this document, the registry data published
by ARIN are not the same RPSL as that of the other registries (see
[RFC7485] for a survey of the WHOIS Tower of Babel); therefore, Babel). Therefore, when
fetching from ARIN via FTP [RFC0959], WHOIS [RFC3912], the
Registration Data Access Protocol (RDAP) RDAP
[RFC9082], etc., the "NetRange" attribute/key must be treated as
"inetnum", and the "Comment" attribute must be treated as "remarks".
[rpki-client] can be used to authenticate a signed geofeed file.
9. Security Considerations
It is generally prudent for a consumer of geofeed data to also use
other sources to cross-validate the data. All the security
considerations of [RFC8805] apply here as well.
The consumer of geofeed data SHOULD fetch and process the data
themselves. Importing datasets data sets produced and/or processed by a third-
party
third-party places significant trust in the third-party.
As mentioned in Section 5, some RPSL repositories have weak, if any,
authentication. This allows spoofing of inetnum: objects pointing to
malicious geofeed files. Section 5 suggests an unfortunately complex
method for stronger authentication based on the RPKI.
For example, if an inetnum: for a wide address range (e.g., a /16)
points to an RPKI-signed geofeed file, a customer or attacker could
publish an unsigned equal or narrower (e.g., a /24) inetnum: in a
WHOIS registry that has weak authorization, abusing the rule that the
most-specific inetnum: object with a geofeed reference MUST be used.
If signatures were mandatory, the above attack would be stymied, but
of course that is not happening anytime soon.
The RPSL providers have had to throttle fetching from their servers
due to too-frequent queries. Usually, they throttle by the querying
IP address or block. Similar defenses will likely need to be
deployed by geofeed file servers.
10. IANA Considerations

Appendix A. Example
This appendix provides an example, including a trust anchor, a
Certificate Revocation List (CRL) signed by the trust anchor, a CA
certificate subordinate to the trust anchor, a CRL signed by the CA,
an end-entity end entity certificate subordinate to the CA for signing the
geofeed, and a detached signature.
The trust anchor is represented by a self-signed certificate. As
usual in the RPKI, the trust anchor has authority over all IPv4
address blocks, all IPv6 address blocks, and all Autonomous Systam System
(AS) numbers.

Signature authority for AS numbers is not needed for geofeed data
