I think the whole thing is a bit of a crock; adding integers to inet
addresses doesn't make a lot of sense logically. Perhaps what is
really wanted is functions on CIDR net identifiers, for instance
first_address('10/8') = 10.0.0.0
last_address('10/8') = 10.255.255.255
prior_address('10/8') = 9.255.255.255
next_address('10/8') = 11.0.0.0
which would have obvious extensions to IPv6 without having to bring
numerics into the picture.
What are the actual applications for adding integers to inet addresses?
The one Kristian mentions seems to be covered by next_address(), but
are there others?
