and i suggest that "the last tuple" is quite unclear. if you mean
the last octet in ipv4, it is usually zero as a /24 is assigned. if
you mean the last octet in ipv6, it also is usually zero, in fact
the whole last 64+ bits are.
I read the above as saying "the last tuple of the network portion", rather
than of the whole 32/128 bits... So wouldn't that make it clearer?
