AOL registration ip's
 

Have been looking into a problem that a few members are having lately (all AOL users) and I have noticed that the ones having the problems have the exact same registration ip recorded in their admincp profile with other members.

Right now I have found 6 members who share the same ip address with other members and they are all AOL users. So two members have the same ip* then another two have the same ip but different ip then the first two* and the last two again the same ip but different than the others.

Is this normal? I know that AOL uses open proxies but when they are registering shouldn't the ip get checked and not allow the same one to be used?

Thanks!
