Concept
.local
Résumé
The domain name .local is a special-use domain name reserved by the Internet Engineering Task Force (IETF) so that it may not be installed as a top-level domain in the Domain Name System (DNS) of the Internet. As such it is similar to the other special domain names, such as .localhost. However, .local has since been designated for use in link-local networking, in applications of multicast DNS (mDNS) and zero-configuration networking (zeroconf) so that DNS service may be established without local installations of conventional DNS infrastructure on local area networks.
The Internet Engineering Task Force (IETF) reserves the use of the domain name label .local as a special-use domain name for hostnames in local area networks that can be resolved via the Multicast DNS name resolution protocol. Any DNS query for a name ending with the label local must be sent to the mDNS IPv4 link-local multicast address 224.0.0.251, or its IPv6 equivalent FF02::FB. A domain name ending in .local may be resolved concurrently via other mechanisms, for example, unicast DNS.
RFC 6762 was authored by Apple Inc. employees Stuart Cheshire and Marc Krochmal, and Apple's Bonjour zeroconf networking software implements mDNS. That service will automatically resolve the private IP addresses of link-local Macintosh computers running MacOS and mobile devices running iOS if .local is appended to their hostnames. In addition, Bonjour devices will use those .local hostnames when advertising services to DNS Service Discovery clients.
Most Linux distributions also incorporate and are configured to use zeroconf. By default, each computer's Avahi daemon will respond to mDNS hostname.local queries, and most shell commands and application program calls that attempt to resolve such names are routed to that daemon by the default hosts: line in the Name Service Switch configuration file. It is also possible to configure the nss-mdns modules and Avahi to resolve hostnames with other pseudo-TLDs.
