At NCSSM, there are, at any point in time, thousands of devices connected to our network, but we have only a few hundred public addresses available to us. It would be impractically expensive to obtain individual public addresses for each device on our network, so most devices share a single public address. (The rest are reserved for servers and special purposes.)
Moreover, keeping the network secure would be must more difficult if we were to give end-user devices public addresses.
The process of translating from multiple on-campus addresses to the shared public address is called NAT. Home and small-office routers do the same (on a smaller scale) to allow multiple devices to connect to a single home/small office Internet connection. but there are differences between Enterprise NAT and Home/Small-Office NAT.

The Xbox (and other gaming consoles) recognize three NAT types:
With an OPEN NAT type, you’re able to chat with other people, as well as join and host multiplayer games with people who have any NAT type on their network.
With a MODERATE NAT type, you’re able to chat and play multiplayer games with some people; however, you might not be able to hear or play with others, and normally you won’t be chosen as the host of a match.
With a STRICT NAT type, you’re only able to chat and play multiplayer games with people who have an OPEN NAT type. You can’t be chosen as the host of a match.
At NCSSM, as with all enterprise networks employing NAT, your gaming devices will most likely report using STRICT NAT.
