[I'm being |> serious, not sarcastic.] | |Hmm, so, you should have an IP just dangling in mid-air? *shakes his head* Sure. I'd prefer not be listed in a DNS zone transfer ('host -l') for anyone methodically scanning systems. Doesn't mean you won't scanned -- somewhat like having a private phone number -- but it can't hurt. |And what do you tell users when they try to use sites that require 128 bit |encryption and that encryption level requires proper resolution of the |address forward and backward? "Oh, we don't support that, it's not |important..." ? I can hear a herd of users running for other ISPs... Ok, you've perked my interest. What does reverse DNS lookup have to do with 128-bit encryption. You may be implying a specific form of encryption (IPsec or something?). I use 128-bit/1024-bit encryption in my e-mail daily, without reverse DNS ;-) Randall -- Randall Hopper aa8vb@nc.rr.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
