If you are in India and have a BSNL DataOne broadband internet connection, you might have experienced this problem quite often. Your connection appears to be OK and all lights glowing on the modem. Your LAN icon is also showing connected. However, you are not able to open any website.
This is a common problem faced by BSNL broadband users. The DNS server they use is not that active to respond.
DNS stands for Domain Name Server. When you type www.google.com, the DNS server converts the name into an IP address of Google. Then it follows the IP address to fetch you the webpage.
Now, due to a defective DNS server system, your typed address can not get resolved into IP. So you reach nowhere.
Verify if this is the problem:
Try typing the IP of the website instead of the name. That is, type http://188.8.131.52/ instead of http://www.google.com and you should reach the Google website.
Some other websites’ IP for easy reference:
If you are able to open the website by typing the IP as mentioned above, then we are sure it was the problem with BSNL’s DNS servers.
How to solve this:
Open your network connection properties. Usually you open it by double clicking on the LAN icon on your system tray, then going to ‘Properties’ and then ‘Internet Protocol (TCP/IP)’ properties.
Now choose to ‘Use the following DNS server addresses’ and enter the two addresses 184.108.40.206 and 220.127.116.11 for OPENDNS.
If OPENDNS doesn’t work, try GOOGLE’S FREE DNS SERVICE:
18.104.22.168 and 22.214.171.124
Now save and close everything. Your internet should behave normal now.
