A Canonical Name (CNAME) record is a type of resource record in the Domain Name System (DNS) that maps one domain name (an alias) to another (the canonical name). [1]This can prove convenient when running multiple services (like an FTP server and a web server, each running on different ports) from a single IP address.
It is a successor to the WHOIS protocol, used to look up relevant registration data from such Internet resources as domain names, IP addresses, and autonomous system numbers. While WHOIS essentially retrieves free text, RDAP delivers data in a standard, machine-readable JSON format. [1]
The domain name system acts like a large telephone directory and within is the master database, which associates a domain name such with the appropriate IP number. When the domain name is registered/purchased on a particular registrar's "name server", the DNS settings are kept on their server, and in most cases point the domain to the name ...
For example, to do a reverse lookup of the IP address 8.8.4.4 the PTR record for the domain name 4.4.8.8.in-addr.arpa would be looked up, and found to point to dns.google. If the A record for dns.google in turn pointed back to 8.8.4.4 then it would be said to be forward-confirmed.
Anycast rendezvous point can be used in Multicast Source Discovery Protocol (MSDP) and its advantageous application as Anycast RP is an intra-domain feature that provides redundancy and load-sharing capabilities. If the multiple anycast rendezvous point is used, IP routing automatically will select the topologically closest rendezvous point for ...
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 ...

In 1993 the U.S. Department of Commerce, in conjunction with several public and private entities, created InterNIC to maintain a central database that contains all the registered domain names and the associated IP addresses in the U.S. (other countries maintain their own NICs (Network Information Centers) -- there is a link below that discusses Canada's system, for example).
