How to Fix a DNS problem
July 18, 2008 | 6:37 pmThe “real” way:
- Have a server running on GoGrid. You can access the machine ‘coz you know it’s IP address and hence no DNS is involved.
- Login to said server.
- Ping Google.com from said server to grab Google’s IP Address
- Enter Google’s IP Address in address bar, and watch with elation as it works.
- Ask Google to solve the problem.
- Google Answers
- Blog about your nerdiness.
The shorter, not-so-nerdy-but-still-geeky way:
- Find your Network connection properties, and then the TCP/IP v4 properties (I’m not telling you how – remember, this is still the not-so-nerdy-but-still-geeky version)
- Use the following DNS Servers (Donno where they are from, they work (and worked even when OpenDNS didn’t) – 4.2.2.1 and 4.2.2.2 (No, ain’t kidding. These WORK!(Easy to remember as well)))
- Bingo!
In other non-tech news, I ain’t dead – it’s just that I was caught up with college stuff. Now that it’s over, I’ll be back
4.2.2.[1-6] are Level 3 's DNS servers. They are distributed
Vimal George | July 29, 2008 | 10:44 pm4.2.2.[1-6] are Level 3 ’s DNS servers. They are distributed all over the world. (sounds impossible right). The black magic involved went way over my head.
There is a pretty nasty DNS vulnerability that was leaked onto the net by accident last week. You might want to statically assign Level3 or OpenDNS servers to all your machines. The alternative is a potential DNS spoofing+phishing attack based on the vuln. Seems only 60% or so DNS servers have been patched till date. My default Airtel GPRS DNS servers were only patched 2 days ago.

P.S: always bookmark a google IP or two. This has always been my golden rule for survival on the Indian Internet. lol.
