Hello,

I've written some off-Internet IPv6-only software. There are generally
only two reasons to do so:

1. You need the software to self-address a link local Interface. IPv4
doesn't do this well. It's useful for experiments in self-constructing
networks.

2. You're doing something funky with networking that has to live in a
large address space.

Since the IPv6 software APIs are 100% backward compatible with IPv4
there aren't a whole lot of other reasons to write software that's
IPv6-only.

Regards,
Bill Herrin
