Directory Name Service is a TCP/IP based name resolution service which is used to resolve a host name to its associated IP address.
Steps involved in resolving names to IP Addresses are:
Web address entered in to your Web browser from workstation (resolver)-www.proprofs.com/support
DNS client (resolver) needs an IP address for this name and sends a request to its designated DNS server for a translation for the address www.proprofs.com
DNS server receives the resolver's request and searches its database for a resource record for www.proprofs.com, it finds 66.226.90.62.
Once the DNS server receives resolution for the address www.proprofs.com, it passes the information back to the requesting client (resolver): 66.226.90.62.
After the browser client receives an IP address resolution, it sends a request to the 66.226.90.62 address requesting a Web page for the directory /support.
The Web server (66.226.90.62) returns the Web page located at /support to the requesting Web browser client.
