DNS server ( Local DNS server)

DNS is key to many network services such as

  1. Internet browsing
  2. Mail server
  3. Web server
  4. Gaming
  5. Video streaming and more.

Almost all traffic on the Internets depends upon the DNS servers. Most ISP (Internet Service Provider) have their own caching dns server to reduce network load. But, how do you find out DNS server IP address? How do you find out current DNS server IP address? Under Linux, FreeBSD and all UNIX-like operating systems you have a file called /etc/resolv.conf file. It is often know as resolver configuration file.

The resolver is a set of routines in the C library that provide access to the Internet Domain Name System (DNS). The resolver configuration file contains information that is read by the resolver routines the first time they are invoked by a process.

To see your DNS server address type following command as shell prompt:

$ cat /etc/resolv.conf

nameserver 203.54.1.20
nameserver 203.54.1.21

Where: Nameserver 203.54.1.20 : It is Name server IP address (in dot notation) of a name server that the resolver should query. All your application will use this IP address for DNS purpose.
