I just wanted to know is it possible to find a persons IP through their website when they dont give it out publicly?

just ping their site that'll give you the ip. it usually works unless they have a firewall up.

go to the command prompt and type:
ping www.lissaexplains.com

You mean Programs > Accessories > Command Prompt and type that and it gives the IP? I ask it that and it gave me what looks like an IP: 62.64.187.18 but did I do it right? I typed ping SITEURL

edit: I tried to find my own IP when using that that way and it wasn't correct so I guess I'm not doing it right?

yip, kinda cool huh :) it gives you the domain names ip address not yours.

if you want your ip address try 'ipconfig'. this command will give you your ip address. which means it should be different then the one you got from 'ping'

so could you use DENY IP ADDRESS (as in banning) by using the domain's IP?

i don't think 'deny ip' is a dos command :/ but lissa has a little thingy on how to block ip address http://www.lissaexplains.com/html6.shtml#block

yes, I know how to deny it, I just don't know how to find their IP out that's what I'm asking (sorry i was a bit confusing there)

ping their site and it'll give you their ip. go to 'All Programs' --> 'Accessories' --> 'Command Prompt' type in 'ping www.domain.com'. the results of the ping will look like the one below:

C:\>ping www.lisaexplains.com

65.192.28.38 is lissa's ip address and that's all there is to it :)

but to answer your question, no, you can't block someone using their domain's IP address. you need their IP, the one used by their ISP.
