using host.allow on dynamic addresses

I´ve been receiving some of this lines on my apache access log:

200.67.17.221 - - [28/Apr/2003:17:46:05 -0500] "GET
/default.ida?XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

>From what I´ve read, I can put on hosts.allow these addresses to avoid this
type of problem, but what if some of those addresses are dynamic? If one
user has an infected PC with a dialup access to Internet, and then hangs up
and another user receives this same address, even if his PC isn´t infected,
he couldn´t visit my site, right?
