Technical Summary
Certain individual IP addresses and IP address ranges are treated
specially by network implementations, and consequently are not
suitable for use as unicast addresses. For example, IPv4 addresses
224.0.0.0 to 239.255.255.255 are multicast addresses [RFC2606],
with 224.0.0.1 being the "all hosts" multicast address [RFC1112]
[RFC5771]. Another example is 127.0.0.1, the IPv4 "local host"
address [RFC5735].
Analogous to Special-Use IPv4 Addresses [RFC5735], DNS has its own
concept of reserved names, such as "example.com", "example.net",
and "example.org", or any name falling under the top level
pseudo-domain "invalid" [RFC2606]. However, "Reserved Top Level DNS
Names" [RFC2606] does not state whether implementations are
expected to treat such names differently, and if so, in what way.
This document describes what it means to say that a DNS name is
reserved for special use, when reserving such a name is appropriate,
and the procedure for doing so.
