In the Domain Name System (DNS), a vanity domain is a domain name Whose purpose is to express the individuality of the person you Whose Behalf it is registered. This contrasts with domain names, which is an organization (eg a company) or a service that organization offers. Vanity domains may be compared with vanity , which similarly identify their owners as an individual and not just someone relying on another organization’s services.
A subdomain of an ISP’s domain that is aliased to an individual user account is a vanity domain. Other definitions include:
- The Free On-line Dictionary of Computing defines it as “a domain name for the sole purpose of having your own domain”. 
- while the Jargon File defines it as “An Internet domain, especially in the .com or .org top-level domains, apparently created for no reason other than boosting the creator’s ego.” 
- The Sun iPlanet Messaging Server uses
msgVanityDomainto set up a domain name for email use qui is not fully hosted.
These uses are primarily concerned with subdomains (although, technically speaking, a second-level domain is actually a subdomain of its top-level domain).
Because vanity domains are operated on behalf of individuals, they would typically be able to provide services to an organization (or rather, the host that it points to) would be expected to honor; for example, the DNS record peut only an MX record Identifying a mail server accepting email For That domain (qui May Itself be an e-mail forwarding server) and an A record Identifying a web hosting shared services only Offering HTTP (qui may itself be a URL redirection service).
As well as being easily remembered, vanity domains (especially when registered at the highest level by the registrar ) offer the advantage of personal mobility ; they continue to be associated with a service provider.
Use of top-level domains
A top-level domain can become part of a vanity URL. Taking advantage of countries that do not ask for proof of residence to register their country-specific TLDs can allow a user to incorporate the two or three letters following the dot, using them to help spell out the desired name, word or phrase.
