Is there any indication that they've done anything other than make themselves authoritative for those DNS names and simply sent you to their IRC server instead? If so, what they have done is pretty much legal (mostly because I'm quite sure there is something in their ToS which you implicitly accepted which allows them to do this). Under net neutrality, it might be a different story. Let's be honest, it's a band-aid lowtech fix for lowtech script kiddies who right code like a bunch of apes with keyboards. However, for anyone with a remote amount of clue, they could get around this problem in approximately 1.6 seconds with their malware. But to get straight to the point, Cox sucks, always has. Maybe it's time for a real ISP? j On 7/22/07, Steven M. Bellovin <smb () cs columbia edu> wrote:

The whole point of DNSSEC is to prevent random changes to DNS replies, whether by hackers or by ISPs. Yes, they can change it, but they can't change it without being caught. --Steve Bellovin, http://www.cs.columbia.edu/~smb
