NAT
Network Address Translator generally applied by a
router, that makes many different IP addresses on
an internal network appear to the Internet as a
single address. For routing messages prop
your network, each device requires a unique IP
address. But the addresses may not be valid outside
your network. NAT solves the problem. When
devices within your network request information
from the Internet, the requests are forwarded to the
I
nternet under the router's IP address. NAT
distributes the responses to the proper IP addresses
within your network.
