DNS (RR)TYPE

Originally QTYPE was a superset of TYPE; RFC 6895 now defines:

There are three subcategories of RRTYPE numbers: data TYPEs, QTYPEs, and Meta-TYPEs.

ANY

QTYPE 255 (“*”) doesn’t seem to have an official mnemonic; ANY is used in most tools though.

The ANY mnemonic conflicts with the QCLASS ANY though…
