Feature proposal: use names instead of IPv6 addresses

[Ivan Vilata i Balaguer]

Hi all,

I'm doing some experiments with IPv6 and I've seen that the following statement
in an nginx ``server`` block::

    listen www.example.com:80;

Binds nginx to www.example.com's IPv4 address, but not to its IPv6 address if
it has one (e.g. the name has an ``AAAA`` entry in DNS).  I'm, however, able to
specify the IPv6 address directly::

    listen [1111:2222:3333::1]:80;

But using the name inside the brackets yields an "invalid IPv6 address" error::

    listen [www.example.com]:80;

So, wouldn't it be nicer if nginx supported this syntax?  Or maybe I'm missing
something?

Another possibility would be for nginx to automatically bind to both IPv4 and
IPv6 addresses associated to the name given in the ``listen`` directive, but I
guess this should need more elaboration and some use cases.

Thanks,

::
