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 so the response can 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, 172.16.254.1 (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.
