How to find IP Address

Definition: 

            Internet Protocol Address (or IP Address) is an unique address that computing devices use to identify itself and communicate with other devices in the Internet Protocol network. Any device connected to the IP network must have an unique IP address within its network. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify a network device to deliver mail message, or call ("view") a website. 
Most networks use the Internet Protocol version 4 (IPv4) standard that features IP addresses four bytes (32 bits) in length. The newer Internet Protocol version 6 (IPv6) standard features addresses 16 bytes (128 bits) in length.

To find any website IP:

 Type it in your terminal.
                           
                           $ping www.example.com
                                     or
                           $nslookup  www.example.com
                                  or 
           Go to http://www.domaintools.com/
                     http://network-tools.com


       
To find your local IP: 
                       
                           In windows   open your command prompt
                      C:\  ipconfig
