I can't give you a NOC contact, but I can perhaps fill in some of the routing history of the situation. Using GRADUS (http://gradus.renesys.com), I identified the networks from your description (hopefully the right ones :), looked into the patterns of advertisement, and reconstructed the timeline (all times GMT). None of these blackholing more-specifics were being advertised before 19th November 2002. The sequencing of events suggests to me that all six networks "belong to" and are being managed by a single organization. Someone from BBN may be able to shed more light regarding the "ownership" of the 220.127.116.11/24 subnet. 19 Nov 2002 (19:12) First route. Genuity starts originating 18.104.22.168/24, and continues to do so for 51 days. 22 Nov 2002 (18:11) Supernet starts originating 22.214.171.124/22. 02 Dec 2002 (20:03) Supernet starts advertising 126.96.36.199/24. 10 Jan 2003 (01:04) Supernet starts originating 188.8.131.52/24. 10 Jan 2003 (17:00) Genuity abruptly stops originating 184.108.40.206/24, leaving them providerless. 10 Jan 2003 (20:12) Supernet takes over origination of 220.127.116.11/24 as well. 15 Jan 2003 (13:26) Supernet starts originating 18.104.22.168/24 and 22.214.171.124/24 together. 20 Jan 2003 (23:34) Your customer starts advertising the full legacy B space (126.96.36.199/16), single-homed out of AS26797. It has not been routable to this point. 22 Jan 2003 (17:00) AS2116 starts advertising the /16 as well. SuperNet is now blackholing your customer by advertising the six more-specifics.
