i know that lol..but i want to know how danasoft.com knows this or what they use to detect it.

It's so easy, any website you visit knows that information. The people that have those in their sigs cant see your IP, only the person who is viewing it and the server know it.

It's the same thing as when you go to a site such as whatsmyip.com

 

[Shane]

only the person who is viewing it and the server know it.

Thats what i thought but i just wanted to make sure

thanks for all replies

It's just simple javascript you can use.

getHostAddress(); - will give the ip addy

getHostName(); - will give your hostname

dude its very simple its your computers Caller id IP adress like telephone number

same concept as caller id

ya even here they have it. if ian or a admin wanted to ban someone they can look up there ip on this site. BEWARE THEY ARE WATCHING . i know for my work, we use urchin. it records what internet you use, ip, os, service pack (for windows), how long, how many hits, where you went after. seems illegal to me but thats the internet for ya

You can get all that stuff from the webserver, it's all sent though the HTTP headers. boucin is correct as well, you can use javascript to find it all out too
