|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.

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 ;-)
