Does Bind 9.2.1 work this so that it can receive packets, when IPv6 is
also enabled, from IPv4 addresses using TCP without
'match-mapped-addresses yes', or is that a separate problem?

Bind9 trys to bind :: and all ipv4 addresses on the node.

Yes, but binding those IPv4 addresses _for TCP_ failed after binding to 
::, at least previously.  That worked e.g. on BSD.  Does that work now, 
too?

I.e. I have two boxes, both running Bind 9.2.1.  Linux gives:

$ netstat -an | grep :53
tcp        0      0 :::53                   :::*                    LISTEN      
udp        0      0 193.94.160.1:53         0.0.0.0:*                           
udp        0      0 127.0.0.1:53            0.0.0.0:*                           
udp        0      0 :::53                   :::*    

and BSD gives:

# netstat -an | grep .53
tcp6       0      0  ::1.953                *.*                    LISTEN
tcp4       0      0  127.0.0.1.953          *.*                    LISTEN
tcp4       0      0  127.0.0.1.53           *.*                    LISTEN

tcp4       0      0  193.166.187.10.53      *.*                    LISTEN
tcp6       0      0  *.53                   *.*                    LISTEN
udp4       0      0  127.0.0.1.53           *.*                    
udp4       0      0  193.166.4.206.53       *.*

udp6       0      0  *.53                   *.*

Will this work too?
