Airtel DSL DNS Servers are overloaded sometime it takes up to 2 seconds or query get just timed out.

I had switched to OpenDSN server - which is a free and powerful DNS service. Use following DNS server address:

Windows XP change DNS server
You can Click on Start button > Settings > Network connections
Double click on Local Area Connection or your Internet connection
Click on Properties button
Select Internet Protocol (TCP/IP)
Click on Properties button and Look for Preferred DNS Server:
Setup NS1 - 208.67.222.222
Setup NS2 - 208.67.220.220

Save and close the windows. If you are using old version of windows you may need to reboot the system.

To test new setting go to Start > Run > Type cmd
Type nslookup command
Now type domain name
yahoo.com
google.com

Linux change DNS server
Please read following tnstructions:

If you are using a Linux, you can further increase speed by installing squid local proxy server and dns dnsmasq caching server.
