Binding to both IPv4 and IPv6 addresses
Is it possible to bind a CouchDb server to both IPv4 and IPv6 addresses?
I'm running CouchDb 1.2 on Windows 7 and I seem to be able to bind to
the public IPv4 address with bind_address = 0.0.0.0, or to the IPv6 address
with bind_address = ::, but I don't know if there is a way to specify both.

Thanks Dave. I also saw that bit of code and was hoping there was something I could do in the CouchDb config to influence it, but apparently not.
It's actually not critical to do this: the underlying problem is the .NET WebRequest trying the IPv6 address for localhost before the IPv4 one, which introduces a one second delay to calls. I can work around it by resolving localhost to an IPv4 address before the WebRequest. That's probably easier than the alternatives.

Hi Nick,
CouchDB uses Mochweb to handle the http/ip layer. Reading
https://github.com/mochi/mochiweb/blob/master/src/mochiweb_socket_server.erl#L174
implies that it might be if the OS can handle it. But I'm not sure I read
it right,
or if Windows allows you to do that.
If not, your best bet is likely to set up a teredo forwarder of some sort.
This is out of my experience, but

has some stuff that might point you in the right direction.
A+
Dave
