It's not iffy, it's completely unreliable.  For example, all requests
from AOL users arrive through a small number of IP addresses of AOL
proxy servers.  Millions of AOL users share a few hundred IP addresses
and there's no way to tell them apart by address.  Also, there's no
consistent relation between an AOL client session and which AOL proxy
server it uses.  If an AOL user visits your page and hits "reload"
five times, the resulting six requests can come from six different IP
addresses.
