Server Not Found, Fix DNS Problems.

Sometimes wierd things happen,
Server Not Found www.google.com
Or you can get www.kitiyo.com but not rgb.kitiyo.com
Or you cannot get www.somesite.com but your friend can!
Silly DNS Problems.

When we browser and enter a url in the browser's address bar, one of the first step is to resolve the domain name. ie convert the www.server-name.com to the IP address.

If our dns server settings are wrong or if the dns server does not respond, we get the familiar
Server Not Found page.

There are some ways to resolve this.

1. Get the correcet DNS IP address from the ISP, and get more than one.
2. Get some free DNS IP address, some of which are given below
   

   67.138.54.100
   207.225.209.66
   208.67.220.220
   208.67.222.222
   

3. Install a local caching dns server that caches servernames and ip address so that subsequent visits can be made faster since resolving is done locally.
   like Ubuntu debian package dnsmasq

Adding name servers
Windows :

• Click TCP/IP and then click Properties.
• Add Primary and Secondary DNS Servers.

Linux:
Add the lines to /etc/resolv.conf

nameserver IP.ADD.RES.SSS
nameserver 67.138.54.100

Any more ideas ?
