Re: [PATCH] IPV6_V6ONLY Support, v2 (is Re: [PATCH] IPv6: Allow Both

Hello!

Late question:

::, at least previously.  That worked e.g. on BSD.  Does that work now, 
too?

Provided it uses IPV6_V6ONLY.

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

...

Will this work too?

No.

The question follows: what the hell does it make this? What is special
in ipv4 that it needs to bind to its addresses? With IPV6_V6ONLY connections
to all the IPv4 addresses but listed ones will be refused. I guess it is
not _that_ thing which bind expects.
