Protocol Registration Forms
Registration forms are listed below. If we don’t have a registry-specific form, the General Protocol Registration Request Form should be used.
Before you submit a request, check the registry for its registration procedure(s) and reference document(s). Common procedures are defined in RFC 8126, but the RFC that defines the registry may include more detailed instructions. You can find a list of registries here.
Note: if a registration procedure requires RFC publication, it may be possible to obtain an early allocation. Early allocations are marked as TEMPORARY in the registry and must be reviewed annually. Early allocation requests must be submitted by the relevant IETF WG chair. For further requirements, see RFC 7120.
