The various arts of rewriting TCP/IP address headers for various reasons. Some things you can to do with [NAT]:
* Transparently redirect certain protocols/ports to different machines than they were originally addressed, for example when creating a TransparentProxy
* Map multiple IP's onto a single IP (for when you have a segment of internal machines using RFC:1918 addresses and you want to map them onto one realworld IP address)
* Map arbitary IP's onto other arbitary IP's.
+
+For example, some external [ADSL] modems are really routers - you plug them into your network switch and it does address translation between IP addresses on your local network and the single IP address assigned to your account by your [ISP].
