This app is not expensive, but for $2.99 all you get is the bare bones. You have to pay $1.99 in order to get the full version. Other than that it gives you a few things not included in Network Preferences: Router model number, vendor name and it's MAC address. Perhaps more important, for troubleshooting purposes, it provides the Public IP address, though you cannot copy it by clicking on it. You'll have to copy it by hand. I updated to the "full version" but the number is still 1.3, not version 5. Nothing else copies either. So the developer is confused at best. So stay away unless you need these few extra details. Of course I can log into my router to get the same info, but it's a bit of a hassle.
