"DNS adress changing to"

That does sound a tad suspicious. To help determine whether it is or not, try this:

Open a Command Prompt window, type ping then press Enter on your keyboard.

What IP address do you get shown in the square brackets at the top of the output text?

.......I should have mentioned that you need to do the above while your DNS server is set to

Have a look at your hosts file (in Windows\System somewhere) and see if your normal router IP is being transferred to by the hosts file.

"on command prompt i am getting ip address clues"

That's the correct IP address for Google so I'm less concerned that you've got a malware infection. If you have then I would've expected seeing an IP address in China or Eastern Europe. The last DNS hijack I looked at, when the user went to Google in his browser the page was served from somewhere in Russia.

Are you running any security software that might be running as a DNS server? If you're not sure, and you're moderately experienced, then you may be able to discover what's going on by copying and pasting this into a Command Prompt window:

netstat -ano|find ":53"

The far right-hand column shows the PID (process identifier), and using Task Manager you can match the PID to the name of a program or service. You may need to add the PID column to Task Manager, and make sure you click the "Show processes from all users" button. If you discover any process names then post them here.

If you're not aware of any special software you've got installed that's acting as a DNS proxy then all I can suggest is to scan for a malware infection. Run a full scan with your regular anti-virus software first then download, install, and run a "Quick Scan" with the free version of Malwarebytes Anti-Malware - you can get it from here. During installation, if you're prompted to install the free trial of the Pro version then de-select that option.
