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.
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…
an authoritative name server
a mail destination (OBSOLETE - use MX)
a mail forwarder (OBSOLETE - use MX)
the canonical name for an alias
marks the start of a zone of authority
a mailbox domain name (EXPERIMENTAL)
a mail group member (EXPERIMENTAL)
a mail rename domain name (EXPERIMENTAL)
a well known service description
mailbox or mail list information
for AFS Data Base location
for NSAP address, NSAP style A record
for domain name pointer, NSAP style
X.400 mail mapping information
DNSKEY(s) the Child wants reflected in DS
Child-To-Parent Synchronization
transfer of an entire zone
mailbox-related RRs (MB, MG or MR)
mail agent RRs (OBSOLETE - see MX)
“*”, a request for all records the server/cache has available

This method tests for
self
and
other
values to be equal, and is used
by
==
.

This method tests for
!=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.

This method returns an ordering between
self

other
values if one exists.

This method tests less than (for
self
and

<
operator.
