I wish people would actually read RFC 1918.
Category 1: hosts that do not require access to hosts in other
enterprises or the Internet at large; hosts within
this category may use IP addresses that are
unambiguous within an enterprise, but may be
ambiguous between enterprises.
Category 2: hosts that need access to a limited set of outside
services (e.g., E-mail, FTP, netnews, remote login)
which can be handled by mediating gateways (e.g.,
application layer gateways). For many hosts in this
category an unrestricted external access (provided
via IP connectivity) may be unnecessary and even
undesirable for privacy/security reasons. Just like
hosts within the first category, such hosts may use
IP addresses that are unambiguous within an
enterprise, but may be ambiguous between
enterprises.
Category 3: hosts that need network layer access outside the
enterprise (provided via IP connectivity); hosts in
the last category require IP addresses that are
globally unambiguous.
RFC 1918 addresses for machines that fall in Categories 1 and 2.
