Dynamic DNS is a useful service that allows you to use a fixed and memorable address for your home network even when your ISP changes your home network's IP address. You can often set up DDNS on your router. You can also run a DDNS client on one of your devices, like a computer, a NAS, or a Raspberry Pi.
Dynamic DNS (DDNS) lets you assign an easy-to-remember address so you, your friends, and your family can access your home network with a simple website-like name.
This is one of the better and easier to read descriptions I've seen about this topic. They also cover a few different DDNS providers (including one's built-into many routers), as well as touching on security.
