Re: [DNS] Anyone having any DNS issues?
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

1 edit | 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.

Hoth | 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.

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. |

said by m0unds :iirc, the 4.2.2.1, 4.2.2.2 etc DNS servers offered by VZ are now closed. They are not Verizon DNS servers. They are run by Level 3.
They are still accessible to me:
The fastest are my ISP servers (last pair).

| GTE(I) = Verizon, but the 4.2.2.1/2/3/4 are on Level3's address space.
$ host 4.2.2.2
2.2.2.4.in-addr.arpa domain name pointer vnsc-bak.sys.gtei.net.
Registrant:
Verizon Trademark Services LLC (DOM-384172)
1320 North Court House Road
Arlington VA 22201
US
So they're on L3 address space, but the hostname and everything points to Verizon. |

| The Verizon reference is because of history. Once upon a time there was BBN Planet, a nationwide ISP (nee Bolt, Beranek & Newman). They were acquired by GTE and renamed GTE Internetworking. During this time they implemented a new DNS infrastructure, and put the nameservers in the GTEI.NET domain.
GTE merged with baby bell NYNEX to form Verizon. As the Bell breakup consent decree was still in force, they had to divest the national ISP division, and it became the public company Genuity. Genuity was later acquired by Level(3).
However, Verizon kept ownership the GTEI.NET domain, perhaps because they continued to use it for their local ISP businesses (which they didn't have to divest). And Genuity/Level(3) never felt the need to change the names associated with 4.2.2.x. There was still a pretty tight relationship between Verizon and Genuity after the spin-off -- Genuity actually operated Verizon's DSL infrastructure (at least they did when I was still there, about 5 years ago). |

GTE Internet, which was in 4.0.0.0/8, was spun off from GTE, the ILEC, when Verizon was formed in 2000. It became Genuity, and had no more to do with Verizon than spin-off ATTBI had to do with AT&T Corporation. As Comcast bought ATTBI, without buying AT&T Corporation, so Level 3 bought Genuity (former GTEI) without buying Verizon.
