What is a DNS name server?
A domain name server is similar to a phone book. It tells the Internet programs (e.g. web browsers) where to go by translating the domain name into an Internet (IP) address. Every Internet Service Provider (ISP) has its own DNS servers. You need at least 2 DNS server names to specify who is hosting your domain or web site. You can find out the address of your DNS servers if you are hosting your web site with a web hosting company.
