270 Chapter 7: Managing Address Spaces with NAT and IPv6
?– Static NAT is one-to-one address mapping. Dynamic NAT addresses are picked from
a pool.
?– NAT overloading (PAT) allows you to map many inside addresses to one outside
address.
?– Use the show ip nat translation command to display the translation table and verify
that translation has occurred.
?– To determine whether a current translation entry is being used, use the show ip nat
statistics or clear ip nat statistics commands to check and clear the hits counter.
?– Use the debug ip nat command to verify translation of packets.
Transitioning to IPv6
The ability to scale networks for future demands requires a limitless supply of IP addresses
and improved mobility. IP version 6 (IPv6) satis?¬?es the increasingly complex requirements
of hierarchical addressing that IP version 4 (IPv4) does not provide. IPv6 uses some
different address types that make IPv6 more ef?¬?cient than IPv4. This section describes the
different types of addresses that IPv6 uses and how to assign these addresses.
