Type of NAT in which a private IP address is mapped to a public IP address based on a table of registered (public) IP addresses. Normally, the NAT router on a network will maintain a table of registered IP addresses, and when a private IP requires Internet access, the router will choose an IP address from the table that is not in use by another private IP. Dynamic NATing helps secure a network by masking the internal configuration of a private network and making it difficult for others outside the network to monitor individual usage patterns. Another advantage of dynamic NATing is that it allows a private network to use proven IP addresses that are invalid on the Internet but useful as internal addresses.
