Set up a static IP with an Airport Base Station

If you run a home server, use file sharing on your network or use BitTorrent, you’ll know how inconvenient a dynamic IP address can be. Rather than memorizing a single address for each computer, you need to constantly look up each system. The solution is to set up your router to use static IP addresses. The problem — if you use an Apple Airport base station — is that the setting is often hidden among the advanced features, and even then it can be hard to identify.

I found the solution while browsing around the Airport Utility after my Internet went down. The setting is hidden in the Internet tab, under DHCP. There you’ll find a list that says IP Reservations, which is Apple’s way of saying these computers will each get a dedicated address.

To set up a computer, click the + icon and start the assistant. The key to successfully setting up the entire system is knowing a computer’s MAC address, which can be found from the Airport Utility under logs and statistics (like the picture below). This code of letters and numbers uniquely identifies each computer on your network, so you’ll need to make a note of it and enter it into the Reserved IP assistant.

With the assistant complete, you need to update the settings on the Airport and wait for the computer’s IP lease to reset. Once that is done, you’ll be able to use the reserved IP whenever you access the computer.
