VBulletin Ban IP?
 

Can you ban by IP in Vbulletin? I cant find that option...

Yes.

I can't recall the exact option, but it is there. Try "permissions"

ADMIN CONTROL PANEL > vBulletin Options > User Banning Options > Banned IP Addresses

IP address ban lists: You may ban any IP addresses from registering and posting. Type in the complete IP number (as in 243.21.31.7), or use a partial IP number (as in 243.21.31).

vBulletin will do matches from the beginning of each IP number that you enter. Thus, If you enter a partial IP of 243.21.31, someone attempting to register who has an IP number of 243.21.31.5 will not be able to register. Similarly, if you have an IP ban on 243.21, someone registering who has an IP of 243.21.3.44 will not be able to register. Thus, be careful when you add IPs to your ban list and be as specific as possible.

As with the email ban list, put a space between each IP number. The IP Ban prevents anyone with matching IP number from registering and posting.

TY :) :thumbsup

Theres an addon for vbulletin that will let you screw with users instead of banning ip's its much funnier. If you ban an ip they will just use a proxy. This mod will make the users load times lag , sometimes they get random 404's etc stuff to mess with them..make them think everyone see's the same thing..
