What is a nameserver?
Otherwise known as a domain name server, nameservers are the magic behind the internet. Without them we’d have to remember long numbers (longer than phone numbers!) in order to send mail, surf the web etc. Each computer attached to the internet has an IP number, which is like it’s address. But to get to your favourite web site you type in a name. Behind the scenes nameservers are busily looking up the addresses of the names you type in and tell your web browser where to go. e.g. ns1.dom23.net ns2.dom23.
