The Domain Name System (DNS) is a standard technology for managing the names of Web sites and other Internet domains. DNS technology allows you to type names into your Web browser like www.yahoo.com and your computer automatically find that address on the Internet.
A key element of the DNS is a worldwide collection of DNS servers. A DNS server can also be defined as any computer registered to join the Domain Name System.
A DNS server runs special-purpose networking software, features a public Internet Protocol (IP) address and contains a database of network names and addresses for other Internet hosts.
A Common Problem
Sometimes the DNS errors are really frustrating. Though you are connected to the internet, but quite often the browser come up with the error when you type a address “This page cannot be displayed” with the “Cannot find server or DNS error” at the bottom always shows up.
In fact, this is very common problem. Actually, most of us use automatic settings to obtain the DNS address and by this way connect through the DNS address supplied by our Internet Service Provider (ISP). If the ISP’s DNS cannot resolve the IP address issue of the websites, you will get the above mentioned DNS error.
