Expand description
Application Software:
Are writers of application software expected to make their software recognize these names as special and treat them differently? In what way? (For example, if a human user enters such a name, should the application software reject it with an error message?)
Variants
Application software SHOULD NOT recognize these names as special, and SHOULD use these names as they would other reverse-mapping names.
Application software SHOULD NOT recognize test names as special, and SHOULD use test names as they would other domain names.
Application software SHOULD NOT recognize example names as special and SHOULD use example names as they would other domain names.
Application software MAY recognize localhost names as special, or MAY pass them to name resolution APIs as they would for other domain names.
Link local, generally for mDNS
Application software MAY recognize “invalid” names as special or MAY pass them to name resolution APIs as they would for other domain names.
