Trouble:
We have received many problems in which some sites are not reachable on bsnl dataone or mtnl broadband connection. I myself faced such problem on my own connection. It may has happened with you sometime, when you are not able to access some of the web sites on the other hand all other webs sites are opening properly.
Most common reason for this is wrong dns server entries in your LAN connection properties, or sometimes the DNS server entries might be correct but due to certain errors, the DNS servers used by your connection are not able to locate the web-pages that are not visible to you.
Let’s see how can we fix this issue.
Fix:
In order to solve the problem you need to try alternative DNS servers like OpenDNS , AT&T dns servers or Spectranet dns servers etc.
These are some dns servers sets which you can try (for every set follows the order: primary dns,secondary dns).
- Open DNS servers: 208.67.222.222, 208.67.220.220
- AT&T DNS servers: 4.2.2.1, 4.2.2.2
- Spectranet DNS servers: 203.122.63.152, 203.122.63.154
How to change dns servers in network connections?
1. Open Start >> Control Panel >> Network Connections.
2. Find your internet connection in “LAN or High-Speed Internet”
3. Right click on connection and select properties.(see the image below to see what happens next).
4. Select Internet Protocol Version 4 (tcp/ipv4) and press Properties button. On this screen change the DNS servers by using any one of the dns server settings specified above (as shown in the image below).
Try all the dns server settings one by one at least one of them will work for you.
If you still you are not able access those sites then check if those sites may be blocked by some firewall program or Internet security program installed on your system.
