NAT - network address translation

1. NAT - network address translation
   If it is available to you, NAT often lets you create any size of network you want, without worrying about how much IP space you have been officially allocated. I'm not going to explain what NAT is in detail, because it will be covered in someone else's lesson. In short, it's a way to map large numbers of IPs on to a single IP (or to take a large sparse range such as a Class B and map each address that is actually used on to a small number of Class C's). NAT is worth taking the time to learn, because it can save you a whole lot of effort!
