You can find the IP address of any website by going to a command prompt and typing:
Another way to check the IP address for a website is to use the nslookup command from a command prompt. Most operating systems, whether they are Microsoft Windows, Apple OS X, Linux, etc., provide that tool, which is specifically for looking up IP addresses. E.g., suppose I wanted to look up the IP address of google, I could use the command
nslookup www.google.com as shown below where the command is run on a Microsoft Windows system:
The line immediately below the "Server" line is the IP address of the DNS server that provided the information for google.com. The Addresses line shows an IPv6 address for google.com. IPv6 is a newer version of the Internet Protocol; many websites are now accessible using IPv6, though IPv4 is still widely used. There is no version 5 in use on the Internet; that number was skipped. Most people are more familiar with the IPv4 style addresses, which are the ones shown for google.com below the Addresses line.
You will see that there are four IPv4 addresses shown. Many large companies will have more than one IP address associated with a fully qualified domain name (FQDN), such as google.com. When a system out on the Internet looks up google.com, the IP address that is returned by the DNS servers Google uses won't necessarily be the same each time.
Many large companies with publicly accessible websites use a round-robin DNS technique for associating IP addresses with their web servers, so that if thousands, or even millions, of people may be accessing their servers simultaneously, they won't all be accessing the same server, since the DNS servers will cycle through a list of IP addresses that are returned for DNS queries for an IP address for a web server, thus distributing the load on the company's servers.
Depends on which IP address you're looking for. If you want the one that you use to get to the Internet, which would be the IP address of the interface directly connected to your modem, go to a site like whatismyipaddress.com
However, if you want your actual computer's IP address, for things like forwarding ports from your router, or file-sharing between two computers on your home network, go to start > run > type cmd > in the command prompt window type ipconfig.
