What is the difference between "public" and "private" IP addresses
DSL Highspeed Internet Access
Simply put, "public" IP addresses can be routed across the Internet,
and "private" IP addresses cannot be routed across the Internet. The
single dynamic IP address or block of static IP addresses that Qwest provides to
you are public addresses. They are unique throughout the Internet, and are
accessible from any other user on the Internet. If you are using NAT, the
10.0.0.x addresses that the DSL router assigns to your client PCs are private
addresses, and these addresses cannot be routed across the Internet. The
Internet community has reserved certain IP address blocks for use in private
networks, and the entire 10.0.0.0 network is one of those reserved blocks.
