Re: [DNS] Anyone having any DNS issues?

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

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).

@comcast.net

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.
