Now, the big question is, Why has this worked fine for 6 months, and only decided to crap out today?

I'd guess that it was being rather dumb about trying to look up reverse map entries for these in the DNS. 168.192.in-addr.arpa is delegated to blackhole.ep.net and blackhole.isi.edu, of which the ep.net name servers don't seem to be responding at the moment.

Bill Manning posted something to nanog about that; the ep.net nameservers were being DoSed, so Bill had his providers null-route them for a while until the attack stopped (*shrug*). I bet he never realised that by doing so he would break dial-up access for users on the other side of the planet :) Joe --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
