    en.wikipedia.org/wiki/.local

    As such it is similar to the other special domain names, such as .localhost. [1] However, .local has since been designated for use in link-local networking , in applications of multicast DNS (mDNS) [ 2 ] and zero-configuration networking (zeroconf) so that DNS service may be established without local installations of conventional DNS ...

    en.wikipedia.org/wiki/IPv6_address

    ::1 / 128 – The loopback address is a unicast localhost address. This address corresponds to 127.0.0.1 / 8 in IPv4. If an application in a host sends packets to this address, the IPv6 stack loops these packets back on the same virtual interface. fe80:: / 10 – Addresses in the link-local prefix are only valid and unique on the local subnet.

  9. Zone file - Wikipedia

    en.wikipedia.org/wiki/Zone_file

    The format of a zone file is defined in RFC 1035 (section 5) and RFC 1034 (section 3.6.1). This format was originally used by the Berkeley Internet Name Domain (BIND) software package, but has been widely adopted by other DNS server software – though some of them (e.g. NSD, PowerDNS) are using the zone files only as a starting point to compile them into database format, see also Microsoft ...
