DNS Server
Hi all, do you know what is DNS Server? Here i got from About.Com .
A DNS server is any computer registered to join the Domain Name System.It runs special-purpose networking software, features a public IP address, and contains a database of network names and addresses for other Internet hosts.
DNS Server Hierarchy
The DNS is a distributed system, meaning that only the 13 root servers contain the complete database of domain names and IP addresses. All other DNS servers are installed at lower levels of the hierarchy and maintain only certain pieces of the overall database.
Most lower level DNS servers are owned by businesses or Internet Service Providers (ISPs). For example, Google maintains various DNS servers around the world that manage the google.com, google.co.uk, and other domains. Your ISP also maintains DNS servers as part of your Internet connection setup.
DNS networking is based on the client / server architecture. Your Web browser functions as a DNS client (also called DNS resolver) and issues requests to your Internet provider’s DNS servers when navigating between Web sites.
DNS Servers and Home Networking
Computers on your home network locate a DNS server through the Internet connection setup properties. Providers give their customers the public IP address(es) of primary and backup DNS servers. You can find the current IP addresses of your DNS server configuration via several methods:
* on the configuration screens of a home network router
* on the TCP/IP connection properties screens in Windows Control Panel (if configured via that method)
* from ipconfig or similar command line utility.
