Ip Blocking

[ollmorris]

I have used $REMOTE_ADDR to log the users IP address. I have a script which makes sure a user's IP address is unique. However most people's IP address is dynamic.

On a Vbulletin I got blocked once and I tried connecting, re connecting and I was still blocked due to an IP BLOCKING script. What should I do to make sure the user is blocked permanently!

maybe you have a static one (i.e. the IP of your firewall?)

i have a website where I redirect "banned" users to an alternative page, but there is nothing I can do about dynamic IPs (except block their entire subdomain...)

Users with dynamic IP's cannot be blocked using this method (without blocking a whole range of users). The only other option I know of is to uses either cookies and client information.

Using cookies will not only work if the user has not cleared them out, and they support them. So this is not 100% proof.

You could track user information like, OS, Browser, Screen Colours etc and validate this in conjunction with cookies and IP ranges. This has a much highly likelyhood of been successful.

Thanks very much. What I intend to do is to just change their userlevel.

Thanks again guys/girls
