Users:

Are human users expected to recognize these names as special and use them differently? In what way?

Variants

Normal

Users are free to use these names as they would any other reverse-mapping names. However, since there is no central authority responsible for use of private addresses, users SHOULD be aware that these names are likely to yield different results on different networks.

Loopback

Users are free to use localhost names as they would any other domain names. Users may assume that IPv4 and IPv6 address queries for localhost names will always resolve to the respective IP loopback address.

LinkLocal

Multi-cast link-local usage

NxDomain

Users are free to use "invalid" names as they would any other domain names. Users MAY assume that queries for "invalid" names will always return NXDOMAIN responses.
