Exactly.  Back when I did tech support for an ISP, I used to tell 
callers that having a dynamic IP address made their computer more 
secure, especially on dial-up.  Why?  Well, even if somebody managed to 
get into their computer they'd never be able to find it again once the 
owner had logged off the net because next time they'd have a different 
IP.  Yes, I knew about rootkits back then, but it was a case of KISS. 
Hell, I can also remember assuring callers that email viruses were 
impossible right up until the day the first one hit.
