Your external IP address can provide information to others, such as your location and internet service provider. It’s also attached to emails you send, instant messages, and anything else that goes outside your network unless you use a VPN to hide it. The external IP address is visible to the outside world and is seen by every site you visit. Your home network probably has a wireless router, and the connection or address that router uses to connect to the internet is the external IP address. External or Public IP AddressesĪn external or public IP is the one that the network uses to connect to the outside world or the internet. These IP addresses, for the most part, are only visible inside your home network. This category can be separated further into wireless and wired connections. The connection can be to a laptop, desktop computer, printer, phone, etc. Each connection to a device inside a network has its own address. Internal or local IPs are assigned within a network (like the one your router manages in your home). We will be using different methods to find each of them so let’s quickly go over the difference between the two. There are internal (or local) and external (or public) addresses.

If you've never logged into your router before, check to find the default for yours, then be sure to change it for security.

You'll then need to log in with your router admin and password, which is different than the password you connect to Wi-Fi with. To open your router's management panel, open your browser and type the IP address that appears next to Router in the TCP/IP panel you used earlier. That way, your router knows that your Mac expects to use the same address all the time. For best results, when you set a manual IP address on your Mac, you should also reserve that address in your router.
