The fine print

Required attribution: Not required under CC0; citing IANA is good practice.

Verdict

The authoritative internet protocol registries, alongside pypi-json-api. Licence: CC0-1.0: the IANA licensing terms say "IANA and IETF intend that the Protocol Registries may be freely used by any party for any purpose." and that IANA and IETF affirm their rights are subject to the Creative Commons CC0 1.0 dedication, linking the CC0 1.0 legal code. The scope is the registries, not RFC texts. Some registries, such as port numbers, name individual registrants as public registry data: link only, no contact harvesting. The ICANN terms of service contain no ban on automated access. Rate limits: Not stated. Signal Lab links only.
