What are Domain Names? Domain names are hostnames that provide more memorable names to stand in for numeric IP addresses. They allow for any service to move to a different location in the topology of the Internet (or another internet), which would then have a different IP address.
By making possible the use of unique alphabetical addresses instead of numeric ones, domain names allow Internet users to easily find and communicate with Web sites and other server-based services. The flexibility of the domain name system allows multiple IP addresses to be assigned to a single domain name, or multiple domain names to be assigned to a single IP address. This means that one server may have multiple roles (such as hosting multiple independent Web sites), or one role can be spread among many servers. One IP address can even be assigned to several servers, such as with anycast and hijacked IP space. About Domain Names |
