Re: OpeNDNS
No clue about that, we run our own internal DNS. The thing is that Level 3's 4.2.2.x servers aren't "officially" open to the public like OpenDNS ones are, they've just been around forever and easy to remember. I use them occasionally for troubleshooting or if I need to go to an ISP website to fix someone's computer... |

I wonder if they have some sort of agreement with them. Simply typing DNS in the help section of Verizon.net did not yield any results except for a dial up dns server. |

The reason that the 4.2.2.x DNS servers are frequently referred to as Level3 servers is that the IP NetRange/CIDR is owned by Level3.

1 edit | ask... well I suppose I could have looked it up as well.
Why would level3 have a hold on IP blocks from verizon? You would think that verizon would have many of its own blocks registered.
»www.isp-planet.com/news/2002/lvl···129.html
Level3 bought genuity.com which was the networking GTE I believe. Verizon bought GTE.
Nevermind its a mess that does not benefit me knowing in anyway. I will just assume for the foreseeable future that the Level 3 servers will work with Verizon FIOS |

Why would Microsoft need to use Akamai Technologies servers and IP adresses? The simple answer is that corporations sub contract and sub lease services and properties from other corporations all the time.

I believe the term for this type of perpetual post buyout/merger usage is grandfathering.

said by kieranmullen : I suspect that that is a result of sloppy reverse DNS management on Level3's part.
Verizon (gtei.net) doesn't seep to agree that those hostnames are theirs:
and the servers appear to indicate that they are managed by Level3:

I have 4.2.2.4-5 as my DNS, but when I go to »entropy.dns-oarc.net/test/ it tells me my server names are:
1. 209.244.5.159 (ics2.Atlanta1.Level3.net)
2. 209.244.7.132 (unknown.Level3.net)
No gtei there. As I understand it, those 4.2.2.x addresses aren't actually server addresses, but rather, requests to those addresses are routed to the nearest available Level3.net DNS servers. |
