IP Address

[Zaphod64831]

Anyone here know how to detect the IP of a visitor and react accordingly. I have a web site with a forum that will give me the IP of each person to post a message and I want to be able to program my web site to welcome each person according to their IP address. I know this can be done with cookies but I want to be able to select who I want to welcome and stuff.

I think it would depend on what your back end langauge/platform is exactly. Plus most dial up users will have a different IP address everytime they log on.

Then why is it IP banning works so well?

You could block a whole block of address to ensure that person wouldnt return, but you migh be blocking innocents too.
