[DNS] Anyone having any DNS issues?

I can't resolve a few hosts, including some I own.

Are you using the DHCP-assigned DNS servers from comcast or third party DNS servers? If you're using the DHCP ones, try using the servers provided by opendns.com.

that being said, i'm unable to reach anything across the atlantic. seems like there might be some kind of routing issue.

I just tried OpenDNS's, same issue. Most of my Godaddy domains are dead as well.

Everything seems ok here in Memphis, TN

Comcast is somewhat notorious for regional DNS outages. Perhaps changing to the ever popular 4.2.2.1 as a primary would alleviate your problems.

Tracert it vs the Comcast one ... it was actually closer to me than CC's

If it's a new domain, it could be a caching issue. On windows XP/Vista drop to command prompt as Admin and try a

c:\Documents and Users\ blah blah bla....>ipconfig /flushdns

That will empty your local DNS cache. If running Vista I trust you have your UAC enabled?

EDIT: yep. Me neither - GoDaddy is not found. If only I could justify paying more for what Comacast gives me. Chances are Level 3 is having another bought of sellers envy

iirc, the 4.2.2.1, 4.2.2.2 etc DNS servers offered by VZ are now closed.

208.67.220.220 / 208.67.222.222 = OpenDNS

I'm using the 4.2.2.1 ones now and Im still unable to get to godaddy or the other personal and business sites I have. Funny thing is my buddy who is 3 miles away can access them just fine.

1) That's the notorious part of CC DNS I spoke of

2) Unless you walk over there and see it yourself ... don't believe it

Does it seem odd that now I can't even access my router via the 192.168.1.1 like I used to for the last 7 years?

You need to reboot everything first. Comcast is also notorious for timing out your lease and not giving one back to the same ip# in a timely fashion. Once you can log into your router, Clone your Computers MAC address and see if things tip right side up again.

If I clone my MAC addy will that do anyting negative. I work from home via a VPN connection my company set up and I don't want to clone the MAC Addy if it will screw that up or my wife's labtop that connects wirelessly. The re-boot didnt fix the issue but I can now get on the router.

Fr0zen, if you do a traceroute, do your requests die pretty far en-route to their destination? When I mtr godaddy.com, it dies on the last hop. Same with a few other sites too.

It's not a DNS issue, I don't think-- I don't use the comcast-assigned servers, and the OP changed his to another set and we both have trouble reaching at least one of the same sites. I'm able to resolve everything just fine, the route just fails.

Seems to be an issue on Comcast. Blocking godaddy owned IP addresses (this is from Ccmcast and Godaddy not just a guess)
Godaddy and comcast are working on it as we speak.
