Answer 1: When I hit one of these, I go to http://www.iana.org/protocols
and search within the page. But it isn't black and white; the first one doesn't
exist today under that name. Probably this:

(I sincerely hope you are not really trying to use the highly obsolete TLA format.)

Answer 2: Some RFCs now cite the relevant URLs. For example, RFC 7217 cites:

              IANA, "Reserved IPv6 Interface Identifiers",

I think this is a Good Idea and should be done whenever possible.
