How does it work?
Name servers are part of the Domain Name System (DNS) which is a very complex subject and we would not be able to adequately cover it here, for a simplified version see the DNS FAQ.
Name server management allows you to specify the primary and secondary name servers that will be responsible for queries about where your domain name points to.
What can I use it for?
Point your domain name to our name servers for website hosting, email and free domain parking. Alternatively you can point the name servers to another provider e.g. for website hosting, and you still benefit from being able to control and renew the domain via the LCN system.
