Other Major Networks
The following networks are transit-free networks, even though they have settlement based or paid peering with one or more other networks:
| Name | Headquarters | AS Number | August 2012 degree | Settlement Peer |
|---|---|---|---|---|
| Cogent Communications | USA | 174 | 3537 | Sprint/AS1239 and Level 3 Communications (L3)/AS3356 |
| Hurricane Electric | USA | 6939 | 2180 | Global Crossing (GBLX)/AS3549 and TeliaSonera/AS1299 for IPv4—transit-free for IPv6 |
| OpenTransit (France Telecom) | France | 5511 | 146 | Possibly Verizon Business/AS701 & Sprint Nextel Corporation/AS1239 |
Due to the marketing considerations mentioned above, many people mistakenly believe that other networks are tier 1 when they are not. Because of this, many online resources and forums incorrectly list several non-qualifying networks as tier 1. Below is a list of some of these tier 2 networks which are often listed as tier 1, along with their upstream providers:
- Allstream/AS15290 (Verizon Business/AS701 transit, AT&T/AS7018 transit, Level 3 Communications (L3)/AS3356 transit)
- British Telecom/AS5400 (Global Crossing (GBLX)/AS3549 transit, Level 3 Communications (L3)/AS3356 transit)
- Cable and Wireless/AS1273 (Level 3 Communications (L3)/AS3356, TeliaSonera/AS1299 transit)
- PCCWGlobal/AS3491 (Global Crossing (GBLX)/AS3549 transit)
- tw telecom/AS4323 (Sprint Nextel Corporation/AS1239 transit, paid peering with Level 3 Communications (L3)/AS3356)

Famous quotes containing the words major and/or networks:
“Inanimate objects are classified scientifically into three major categories—those that don’t work, those that break down and those that get lost.”
—Russell Baker (b. 1925)
“The community and family networks which helped sustain earlier generations have become scarcer for growing numbers of young parents. Those who lack links to these traditional sources of support are hard-pressed to find other resources, given the emphasis in our society on providing treatment services, rather than preventive services and support for health maintenance and well-being.”
—Bernice Weissbourd (20th century)
