Ah, true.  Well... the database I use (PostgreSQL) has a "network"
type that accepts both IPv4 and IPv6 addresses.  I'm not sure what the
database I don't use (MySQL) does (or if it even has a network type.)

Right.  I think that's what PostgreSQL may do... not sure.  I'd have
to test to see if it preserves IPv4-ness vs. IPv6-ness for the same
address depending on the input syntax.

We'll all be using IPv6 when the United States uses SI units in everyday
commerce. :(

Don't worry about it... I've integrated a modified version of your
patch into our development version.  I'm travelling next week, but hope
to release a (final?) MIMEDefang 2.68-beta after I return.
