The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link. It is included in Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows 10. [1]
The LMHOSTS (LAN Manager Hosts) file is used to enable Domain Name Resolution under Windows when other methods, such as WINS, fail. It is used in conjunction with workgroups and domains . If you are looking for a simple, general mechanism for the local specification of IP addresses for specific hostnames (server names), use the HOSTS file , not ...
Multicast DNS (mDNS) is a computer networking protocol that resolves hostnames to IP addresses within small networks that do not include a local name server.It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
RFC 6762 was authored by Apple Inc. employees Stuart Cheshire and Marc Krochmal, and Apple's Bonjour zeroconf networking software implements mDNS. [3] 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.
mDNS uses packets similar to unicast DNS to resolve hostnames except they are sent over a multicast link. Each host listens on the mDNS port, 5353, transmitted to a well-known multicast address and resolves requests for the DNS record of its .local hostname (e.g. the A, AAAA, CNAME) to its IP address. When an mDNS client needs to resolve a ...
In computer systems, name resolution refers to the retrieval of the underlying numeric values corresponding to computer hostnames, account user names, group names, and other named entities. Computer operating systems commonly employ multiple key/value lists that associate easily remembered names with integer numbers used to identify users ...
While most rDNS entries only have one PTR record, DNS does not restrict the number. Multiple PTR records are used, for example, when a web server supports many virtual hosts— i.e. multiple hostnames then resolve to a single address, and multiple hostnames will be returned for a PTR lookup for that shared address. However, DNS lookups ...
It can serve the names of local machines which are not in the global DNS. Dnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server. It loads the contents of /etc/hosts, so that local host names which do not appear in the global DNS can be resolved.
