RFC 1918 trivializes the IP addressing by boxing
all hosts into either a "private" or "public" category,
based on their need to access the Internet.
The major thing the RFC misses is the fact that internal
to one of these "public" or "private" hosts, you may have
another, "even more private" network, for example one
that connects the cards within the chassis. Such network
must be (for obvious reasons) completely hidden
from the outside, and thus cannot come from the
"outside" address space. This "outside" space is a union
of the "public" and "private" IP addresses.
Guess what's left? How 'bout 127.0.0.0.
