What is DNS?
All the computers connected to the internet are identified by a unique series of numbers called IP addresses (eg. 18.104.22.168). IP stands for Internet Protocol and these numbers are not easy to remember. Domains were invented because we find it easier to deal with the names, than numbers.
To make it easier to connect specific computers and content, the Domain Name System (DNS) was invented. This is basically an address book which is used to map an easy to remember domain name to an IP address. This then allows any responses sent to the domain name to communicate with the computer that the IP address relates to.
Using DNS is similar to making a phone call with your mobile phone. Your phone dials the number for you and the telephone network uses that number to connect you.
Nameservers form the backbone of the Domain Name System (DNS) as they create the link between a domain name and its email and website services and hold your DNS settings. If you are not using LCN nameservers the DNS settings with LCN will not be used.

Different DNS settings
There are a number of different settings and records that can be set to your Domain. For example, an A record will point your domain to an IP for a website, a CNAME will point a domain to another hostname and MX records points your domain to a mail provider.
