WHAT IS A DOMAIN NAME SYSTEM (DNS)? Domain Name System (DNS) is the registration of a domain namespace with a TOP-LEVEL (root) domain name servers on the internet. There seems to quite a misunderstanding among internet newbies regarding what DNS is .. to make it clear, here is a short list of what DNS is and isn't. A DNS record lists: * The IP addresses for the domain and hosts associated with the domain. * The aliases associated with the domain. * The mail exchanger servers responsible for the domain. A DNS record is NOT: * webservice * mail service * ftp, telnet, finger .. et cetera In short DNS basically is a DOCUMENT which states where services can be found, but no services (other than the information) is provided.
