About IP addresses

Just like a street address determines the recipient of a letter, an IP address (short for Internet Protocol address) is used to identify computers on the Internet. When your computer sends a request, like a search on Google, it tags the request with its IP address in order for the response to be sent back to your computer -- just like a return address on a letter.

How IP addresses look

An IP address is made up of a list of numbers. For example, (for IPv4) and 2001:db8:0:1234:0:567:8:1 (for IPv6).

How IP addresses and geographic locations are related

Your IP address is usually assigned based on a real-world location. To help provide you relevant local results, like the weather in your city when you search for [weather], your IP address may be used by Google to make an educated guess at your general location.

Find your IP address

When you search [what is my ip] on Google Search, you’ll see the IP address of the computer or mobile device you did the search from.
