yes im sure... i checked that out, it was the first thing i did.. the only way i knew was i had the Multiple account login detector (AE Detector) installed...

DementedMindz: Where is your website located at? I can try and take a look at it.

In other news, I made some modifications and this hack is now at version 1.0.4. New features include:
1) Being able to use wildcards in allowed IP addresses, i.e. 192.168.0.*
2) Being able to allow hosts from REMOTE_HOST, i.e. *.aol.com.

Keep in mind that the allowed hosts bit only works if your server does the reverse DNS lookups for REMOTE_HOST from REMOTE_ADDR. That's easily verifiable with a phpinfo script.

see its strange it stops me when i try but a few users who didnt come back for a few days were able to make new names... and they had same ip..

Really, I mean it. If you tell me where your website is, I can try for myself :p Honestly, I would guess that it's because their IP actually did change over the course of a couple days, but yet the notify plugin that you mentioned is notifying you because that checks for Post IPs also. If you would enable post IP bans with this plugin, it would prevent those from happening... though it might also prevent certain people from registering who you want to register.

i looked at there ip its the same ip number its a cable static ip address.... also that hack Multiple account login detector (AE Detector) dont check for there ip its cookie based...

is there any way you could make a feature (with on/off feature in admincp) that is cookie based also like the Multiple account login detector (AE Detector) this way it would auto ban them or stop them???

I might do that some other time, but at this point it's not something I'm especially interested in. The reason is that anyone could simply clear their cookies and reregister, and I'm not interested in making a block that's that easily bypassable.

it seems to work great on Multiple account login detector as it dont use the default vbulletin cookie... this way if they log out it wont clear that cookie...

Did you test your newest version on the wildcards?

thank ，
Installed without a hitch !
