DNS: Domain Name System or Servers

DNS:

The Domain Name System or Servers (DNS), is the way that Internet domain names are located and translated into Internet Protocol addresses. A domain name is a meaningful and easy-to-remember handle for an Internet address. Internet domain names are the names which we use to refer to hosts on the Internet, such as www.webhosting.uk.com while internet protocol addresses are the numbers which routers use to move traffic across the Internet, such as 197.71.123.219 DNS is part of the application layer of the TCP/IP reference model. DNS is implemented using two software components: the DNS server and the DNS client (or resolver).

If you have a domain name with www.123-reg.co.uk, and your web hosting is with www.webhosting.uk.com (for example), the domain name servers would have to be changed to ns1.webhosting.uk.com and ns2.webhosting.uk.com. Your domain name needs to “know” where your website files are. By pointing the DNS to the servers of
webhosting uk, your website will be displayed.
