Question on NAT

hiya ,

Question on nat guys, according to my understanding nat can be used to have private ip address on a network.
And the range for private ip's is
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
But i've seen Nat implemented with ip starting from 65.52.xx.xx for a private network, how is this possible, can any1 explain how this is done.

You can use any addresses you want on your private network. The problem with using addresses other than those laid out by RFC 1918 , is that you may end up using addresses on your network which are in use on the internet. Thus, computers on your LAN will not be able to access those addresses on the internet. You will also need to be careful with your subnetting as you could cut out access to large portions of the internet.

To avoid all this, simple use the addresses specified by RFC 1918.

thanks dalight , was a bit confused when i seen a public ip.going thru the rfc to learn more.
