permits/denys what? (a retorical query)
the point being that there is no practical difference btween
199.2.98.0/24
and 192.0.0.0/24
or 128.0.0.0/24
or 191.255.255.0/24
these prefixes (and delegation points) are valid or potentially valid
in the routing system whereas
192.0.2.0/24
and 172.16.0.0/16
and 192.168.0.0/24
and 10.0.0.0/8
are not.
--bill (off to re-read RFC 1519 and RFC 1918 just to make sure)
