How to find a websites IP address
Finding the numerical IP address of a website is pretty easy, just launch your Terminal and type the following command:
nslookup google.com
You’ll then see something like this printed back at you:
$ nslookup google.com
Server: 192.168.0.105
Address: 192.168.0.105#74
Non-authoritative answer:
Name: google.com
Address: 74.125.127.147
The number underneath google.com is the IP address for Google. Note that some larger websites will have multiple IP responses.
There’s any number of reasons why you’d want a websites numerical address rather than their resolved domain, from troubleshooting DNS problems, to determining domain neighbors, to configuring network settings.

or you could just ping it … ping yahoo.com
hey, 192.168.0.* isn’t it a local ip address?
how come it shows google.com?
