Renesys: Real-Time ISP Market Share Rankings

This is interersting.

Via Renesys.com.

The core of Market Intelligence is Renesys’ Internet Index, the master database of information compiled daily from the Internet’s global routing tables—the real-time map of 180,000 networks and 30,000 organizations worldwide that make up the Internet.

Check here frequently to see which service providers are ranked in the top 25 in 3 categories.

As explained to me by someone from Renesys:

"These are the first rankings of service provider networks that are based on objective data. We put them together based on ~120+ ebgp routing feeds from service providers worldwide. The rankings are based on aggregate views of those data.

"'Customer Base' is kind of obvious. It's based on total downstream prefix-weight (with /8s more important than /24s but not expontially so, or MIT would be one of the
largest networks on the planet :-).

"'Extended Customer Base" is just 'Customer Base' plus a share of the 'Customer Base' of known peers. 'Peering' would be a better, more technical name for it.

"'Customer Growth' is just delta in customer base."

For example, today, the top five (5) listed in three categories:

Customer Base

1. Sprint AS 1239
2. Level 3 Communications, LLC AS 3356
3. UUNET Technologies, Inc. AS 701
