website=None|.localhost is a reserved top-level domain not intended for practical use in the global
Domain Name System (DNS). It was defined in June 1999 by RFC 2606, along with.example ,.invalid , and.test .Its explicit reservation is intended to avoid confusion with the common hostname,
localhost , which is the name of theloopback interface in mostTCP/IP systems. The ".localhost" TLD has traditionally been statically defined in host DNS implementations as having an A or AAAA (address) records pointing to the loopback IP addresses 127.0.0.1 (IPv4 ) and ::1 (IPv6 ) and is therefore reserved for such use. Any other use would conflict with widely deployed algorithms relying on this use.
