A TCP/IP computer network uses two types of IP addresses: public IP addresses, sometimes called external, and private addresses, sometimes called internal or local.
How do I find an IP address?
You may need the public IP address when setting up a file server or website, while the private IP address is useful for communicating with local devices, forwarding ports from a router, or accessing your router to make network changes.
Learn how to find your public IP address in any web browser, how to find your private IP address on a Windows, macOS, or Linux device, and how to find your router's local IP address.
The public IP address is the “face” of the network. It is the single IP address that all of your local network devices use to communicate with the Internet to access websites.
