[−][src]Enum trust_dns::rr::domain::usage::UserUsage
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.
