Brief history of AS 4436: Scruz.net was founded in 1993, and incorporated about a year later. AS 4436 was obtained in 1995 so that scruz.net could connect to MAE West. Scruz.net was acquired in 1996 by Netsource Communications who continued to operate scruz.net as a subsidiary. Netsource Communications went bankrupt in 1997. The scruz.net assets were purchased by Tycho Networks, Inc. (tycho.net) in 1998. Tycho.net added PAIX and PacBell NAP connections. Tycho Networks was acquired in 1999 by DSL.net. DSL.net added PAIX-VA, MAE ATM West, MAE ATM East, AADS NAP, and NYIIX connections. This month, DSL.net switched to an all-transit network model and the peering assets (all NAP connections, associated routers, and the AS number) were acquired by nLayer. Authority/Disclaimer: I was a founder of scruz.net, a founder of tycho.net, and am employed by DSL.net. You'll also note that I am the contact for the 'SCCI' OrgID. Some day all of the paperwork for the entire history will make its way through ARIN, and AS 4436 will be under the nLayer OrgID and the DSL.net IP addresses will be under the DSL.net OrgID. But I've learned to not hold my breath while ARIN works. Matthew Kaufman matthew@eeph.com

Why would nlayer be now using AS4436? It is listed as scruz.net, but as far as I remember scruz was taken overy by DSL.NET (I think that even included their peering agreements) and some of their ip block such as 204.139.8.0/21, 204.147.224.0/20 and others certainly seem to confirm that.
