	PostgreSQL supports this.  Check out the data types.

(yes, 8.2 is the latest, but google to the first hit is easier)

	um, lots of folks have written modules for almost every
language to do ip/subnet comparisons for both v4 and v6.  While
I can understand the desire to use locally derived code, etc..
it does make sense to not reinvent the wheel daily :)

	Speaking of which, someone know of something like the
multicast beacon software that works for unicast stuff that is "free"?

	I've wanted to make some udp-like probe matrix like this
and with all the folks that are asking about cogent, l3, etc.. outages
was thinking that a user community of this type of a test matrix could
be interesting :)  Think like the "internet health report" but with more
sites (possibly hundreds).
