An Internet Protocol (IP) address is used to connect to the Internet and identify devices so that computers, like desktops, mobile devices, and servers can communicate with each other.
An IP address is assigned to your device by your Internet Service Provider, like your cable, telephone, wireless, or carrier company, and is a requirement to use the internet. IP addresses are how computers on the internet recognize one another to send websites or services back and forth. When you visit a website, like google.com, your Internet Service Provider uses your IP address to make sure google.com opens on the device that you’re using.
How Google uses your IP addresses
Google uses IP addresses in almost everything that we do, from building data centers and enabling our engineers to make products like Search or Maps, to getting YouTube videos to your phone.
Your IP address lets Google give you the content you search for. IP addresses are also used in other ways, like to give you relevant results for where you are and to help keep your account secure.
To give local results using your location
IP addresses are roughly based on geography, similar to phone number area codes. This means that any app or website you use, including google.com, can estimate the general area you’re in because of your IP address. When Google estimates the general area that you’re in, Google can provide you with results that are relevant for where you are.
For example, Google could use your IP address to give you the weather forecast for the town you're in when you search for
weather. Learn more about how to manage your location on Google.
Important: The Internet doesn't work without IP addresses. When you use sites, apps, or services like Google, they can usually detect some information about your location.
