Hi!  
My site suddenly “disappeared” after my web host updated and restarted my server.  
After some poking around, I did a ‘netstat’ and only ‘tcp6’ entries were listed for the ports that discourse were supposed to serve (and probably is serving).  
This is a problem for a few reasons.

1. I can’t display ipv6 sites at home
2. My DNS records didn’t list my domain with an AAAA record.

I can solve 2) easilly, but 1) will have to be solved some time later, when my ISP blesses me with a proper connection.

How do I set up Discourse to host on either both ipv4 and ipv6, or ipv4 only?
