12. IANA Considerations
12.1. HTTP Upgrade Token Registration
IANA has registered "connect-ip" in the "HTTP Upgrade Tokens" registry maintained at https://www.iana.org/assignments/http-upgrade-tokens.
- Value: connect-ip
- Description: Proxying of IP Payloads
- Expected Version Tokens: None
- References: RFC 9484
12.2. MASQUE URI Suffixes Registry Creation
IANA has created the "MASQUE URI Suffixes" registry maintained at https://www.iana.org/assignments/masque. The registration policy is Expert Review; see Section 4.5 of [IANA-POLICY]. This new registry governs the path segment that immediately follows "masque" in paths that start with "/.well-known/masque/"; see https://www.iana.org/assignments/well-known-uris for the registration of "masque" in the "Well-Known URIs" registry.
This new registry contains three columns:
- Path Segment: An ASCII string containing only characters allowed in tokens; see Section 5.6.2 of [HTTP]. Entries in this registry MUST all have distinct entries in this column.
- Description: A description of the entry.
- Reference: An optional reference defining the use of the entry.
The registry's initial entries are as follows:
| Path Segment | Description | Reference |
|---|---|---|
| udp | UDP Proxying | RFC 9298 |
| ip | IP Proxying | RFC 9484 |
Table 1: MASQUE URI Suffixes Registry
Designated experts for this registry are advised that they should approve all requests as long as the expert believes that both (1) the requested Path Segment will not conflict with existing or expected future IETF work and (2) the use case is relevant to proxying.
12.3. Updates to masque Well-Known URI Registration
IANA has updated the entry for the "masque" URI suffix in the "Well-Known URIs" registry maintained at https://www.iana.org/assignments/well-known-uris.
IANA has updated the "Reference" field to include this document and has replaced the "Related Information" field with "For sub-suffix allocations, see the registry at https://www.iana.org/assignments/masque.".
12.4. HTTP Capsule Types Registrations
IANA has added the following values to the "HTTP Capsule Types" registry maintained at https://www.iana.org/assignments/masque.
| Value | Capsule Type |
|---|---|
| 0x01 | ADDRESS_ASSIGN |
| 0x02 | ADDRESS_REQUEST |
| 0x03 | ROUTE_ADVERTISEMENT |
Table 2: New Capsules
All of these new entries use the following values for these fields:
- Status: permanent
- Reference: RFC 9484
- Change Controller: IETF

- Notes: None
