Cogent also have a blackhole route-server that they will provide to you to announce /32's for blackholing. The address for this is 66.28.1.228 which is the originator for the 104.31.19.30/3 <http://104.31.19.30/32>2 and 104.31.18.30/32 routes.

Someone else got back: "Abuse cannot not provide you a list of websites that may be encountering reduced visibility via Cogent" I almost wish I had a Cogent circuit just to bring this up with an account rep. Almost. I'd very much so view this as a contractual violation on Cogent's part. Cogent keeps contacting me every year wanting to sell me service. This will be a good one to bring up when they call me next time. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
