dns problems?

[djmwjk]

So I have a REALLY strange problem. I can get to about half of the websites out there on the net, but that means I can't get to about half of them. Luckly my parents still have AOL, and when I connect through AOL to the internet through my DSL everything works fine through AOL. So I know something is up with my internet connection. I've tried the internet on a bunch of computers, and I'm not having any luck. What would cause a computer to only be able to reach about half of the websites out there (I couldn't even reach Tek-Tips.com!)? I'm totally confused since I do IT work for a living, and even though I don't normally deal with internet stuff, my understanding of DNS servers is if they go down then I shouldn't be able to reach anything out there on the net, should I just contact my ISP? Any help / info would be much appreciated!

Like you, I suspect a DNS issue.

I would see if my web browsing experience improved by using one of the public DNS servers out there. There's a list of them below (not all are available but I tried one of the fast 4.2.2.x ones and it was resolving):

Public (Level3) Nameservers (these are OC192's)
4.2.2.1
4.2.2.2 (fast)

4.2.2.6 (fast)

If your web browsing experience improves, you'll have something fairly conclusive to take back to your ISP as a fault.
