The BBC also has an article this morning about this: http://news.bbc.co.uk/2/hi/technology/4051553.stm - ferg -- "Fergie (Paul Ferguson)" <fergdawg(a)netzero.net> wrote: Techdirt has an article this morning that discusses how Lycos Europe is encouraging their users to run a screensaver that constantly "pings servers suspected to be used by spammers" and also suggests that "In other words, it's a distributed denial of service attack against spammers by Lycos." The Techdirt article referenced is on Heise Online: http://www.heise.de/english/newsticker/news/53697 I'd be curious to hear what NANOG readers thoughts are on this.

It seems to me that actually the A6/DNAME > part is a relatively simple one to achieve using current mechanisms. the other issue is multihoming. someone who got done traversing the maze of A6 and DNAME RRs that it took to find your addresses would pretty much know that you were supernetting at the LAN level and that they should use a very short timeout when connecting to each address. when someone gets back multiple AAAA's for you, then you might be multihomed, and folks will do just what they do with multiple A's, which doesn't support rapid renumbering.

More thefts from CO/colo in New York
by Sean Donelan 28 Nov '04

28 Nov '04

On Wednesday night burglars attempted to steal line cards from the co-location area of a central office in White Plains, NY. Police responded to the Verizon building after trouble reports affecting the 911 system, and found two men carrying line cards from the building. http://www.nytimes.com/2004/11/27/nyregion/27theft.html Apparently there is a black market for the cards.
