Hm. DJB released and distributes ucspi-tcp-0.88 from his own web page.

ucspi-tcp6 is simply the 'next generation' of his program adding IPv6 support.
It can be used in environments where both IPv4 and IPv6 support is required for the client/the server.

Thus, ucspi-tcp6 has all the merits of ucspi-tcp plus the new ones. Of course, one has to be cautious about the IPv6 environment. In particular, BSD/MacOS X systems have some problems with the DNS lookup in general (and not restricted to my program). I will provide an analysis on this topic later this year, though a work-around is already provided in ucspi-tcp6.

For the most of this community, IPv6 is a new development. The release is my contribution to support gathering some expertise in this field. In addition, ucspi-tcp6 is a natural successor of ucspi-tcp providing the same level of control for IPv6 connections as available now for IPv4.

Simply try it. It's a snap: package/install -- and you are done. Rejecting global IPv6 addresses ? 2001::/64: deny. Done in rules.cdb.

regards.

Dr. Hoffmann,
 
Thank you for your reply.  That being said, I think I will hold off on applying your update at this time, but will keep a copy of it on hand in case I need to apply the update when the time comes.
