An IP address (short for Internet Protocol address) is used to identify computers on the Internet. It works like a return address would on a piece of mail.
How IP addresses work
When your computer or device sends a request, like a search on Google, it tags the request with your IP address. That way Google knows where to send the response.
What an IP address looks like
Your IP address will be a number, like 172.16.254.1 or 2001:db8:0:1234:0:567:8:1.
Find your IP address
When you search
what is my IP on Google Search, you’ll see the IP address of the computer or device where you did the search.
