one public address to many private address.ie we need only
one public address to connect to internet.

addresses in the IP Address pool, Addresses are dynamically
assign with each private IP whenever any host(assignd with
Private IP Add) try to access Internet.

Registered/Global IP address to many private IP Add. It's
just "Many to one".

DYNAMIC NAT -

IANA provided group of public ip addresses for
communication between stub network ( Internal N/w) to
Internet (outside) network.
Here we map dynamicaly public group Ip addresses with our
stub network ip addresses (private n/w).

OVERLOAD NAT

IANA provided single public ip address for communication
between stub network ( Internal N/w) to Internet (outside)
network.
Here we map dynamicaly public Ip address with our stub
network ip addresses (private n/w) by using source port
number for each pair.Each entry will have separate port
number to identify source/Destination.max ports can assign
4000.
