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. Also, 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 CSV 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.
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.
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 6); 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].
Currently, change control effectively lies in the operator community.
The RPSL, and [RFC2725] and [RFC4012] used by the Regional Internet
Registries (RIRs), specify the inetnum: database class. Each of
these objects describes an IP address range and its attributes. The
inetnum: objects form a hierarchy ordered on the address space.
Ideally, RPSL would be augmented to define a new RPSL geofeed:
attribute in the inetnum: class. Until such time, 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.csv
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.csv
Registries MAY, for the interim, provide a mix of the remarks:
attribute form and the geofeed: attribute form.
The URL uses HTTPS, so the WebPKI provides authentication, integrity,
and confidentiality for the fetched geofeed file. However, the
WebPKI can not 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 4.
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 MUST have, at most, one geofeed
reference, whether a remarks: or a proper geofeed: attribute when it
is implemented. If there is more than one, all are ignored.
If a geofeed CSV 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 4.
When geofeed references are provided by multiple inetnum: objects
that have identical address ranges, then the geofeed reference on the
inetnum: with the most recent last-modified: attribute SHOULD be
preferred.
As inetnum: objects form a hierarchy, geofeed references SHOULD be at
the lowest applicable inetnum: object covering the relevant address
ranges in the referenced geofeed file. 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.
Currently, 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, when fetching from ARIN via FTP
[RFC0959], WHOIS [RFC3912], the Registration Data Access Protocol
(RDAP) [RFC9082], etc., the "NetRange" attribute/key MUST be treated
as "inetnum", and the "Comment" attribute MUST be treated as
"remarks".
4. Authenticating Geofeed Data
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 many repositories is weakly authenticated at best. An
approach where 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.
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. One needs a format that bundles the relevant RPKI
certificate with the signature of 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 a 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 processed by the digital signature
algorithm.
Should the authenticator be syntactically incorrect per the above,
the authenticator is invalid.
Borrowing detached signatures from [RFC5485], after file
canonicalization, the Cryptographic Message Syntax (CMS) [RFC5652]
would be used to create a detached DER-encoded signature that is then
padded BASE64 encoded (as per Section 4 of [RFC4648]) and line
wrapped to 72 or fewer characters. The same digest algorithm MUST be
used for calculating the message digest on 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 SignedData
DigestAlgorithmIdentifiers and the SignerInfo
DigestAlgorithmIdentifier [RFC5652].
The address range of the signing certificate MUST cover all prefixes
in the geofeed file it signs.
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 CSV lines in a geofeed file do.
As the signer specifies the covered RPKI resources relevant to the
signature, the RPKI certificate covering the inetnum: object's
address range is included in the [RFC5652] CMS SignedData
certificates field.
Identifying the private key associated with the certificate and
getting the department that controls the private key (which might be
trapped in a Hardware Security Module (HSM)) to sign the CMS blob is
left as an exercise for the implementor. On the other hand,
verifying the signature requires no complexity; the certificate,
which can be validated in the public RPKI, has the needed public key.
The trust anchors for the RIRs are expected to already be available
to the party performing signature validation. Validation of the CMS
signature on 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.
Validation of the signer's certificate MUST ensure that it is
part of the current [RFC6486] manifest and that the resources are
covered by the RPKI certificate.
2. 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.
3. 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.
4. 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 these steps MUST be successful to consider the geofeed file
signature as valid.
As the signer specifies the covered RPKI resources relevant to the
signature, the RPKI certificate covering the inetnum: object's
address range is included in the CMS SignedData certificates field
[RFC5652].
Identifying the private key associated with the certificate and
getting the department with the Hardware Security Module (HSM) to
sign the CMS blob is left as an exercise for the implementor. On the
other hand, verifying the signature requires no complexity; the
certificate, which can be validated in the public RPKI, has the
needed public key.
The appendix MUST be hidden as a series of "#" comments at the end of
the geofeed file. The following is a cryptographically incorrect,
albeit simple, example. A correct and full example is in Appendix A.
# 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
The signature does not cover the signature lines.
The bracketing "# RPKI Signature:" and "# End Signature:" MUST be
present following the model as shown. Their IP address range MUST
match that of the inetnum: URL followed to the file.
[RPKI-RSC] describes and provides code for a CMS profile for a
general purpose listing of checksums (a "checklist") for use with the
Resource Public Key Infrastructure (RPKI). It provides usable,
albeit complex, code to sign geofeed files.
[RPKI-RTA] describes a CMS profile for a general purpose Resource
Tagged Attestation (RTA) based on the RPKI. While this is expected
to become applicable in the long run, for the purposes of this
document, a self-signed root trust anchor is used.
5. 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
[RFC2818].
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 4, 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.
To minimize the load on RIR WHOIS [RFC3912] services, use of the
RIR's FTP [RFC0959] services SHOULD be used for large-scale access to
gather geofeed URLs. This also provides bulk access instead of
fetching by brute-force search through the IP space.
Currently, 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] 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.
6. 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.
7. 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.
As mentioned in Section 4, many RPSL repositories have weak, if any,
authentication. This allows spoofing of inetnum: objects pointing to
malicious geofeed files. Section 4 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.
8. IANA Considerations
IANA has registered object identifiers for one content type in the
"SMI Security for S/MIME CMS Content Type (1.2.840.113549.1.9.16.1)"
registry as follows:
+=========+==========================+============+

Appendix A. Example
This appendix provides an example that includes a trust anchor, a CA
certificate subordinate to the trust anchor, an 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 System
(AS) numbers.

-----END CERTIFICATE-----
The end-entity certificate is issued by the CA. This certificate
grants signature authority for one IPv4 address block (192.0.2.0/24).
Signature authority for AS numbers is not needed for geofeed data
signatures, so no AS numbers are included in the certificate.
