Hi Chris,

somewhat non-intuitively you need to tell perdition which IPv6
addresses to bind to. For example, you could bind to all addresses
using.

perdition --bind_address '[::]'

Unfortunately while preparing this email I noticed that there is a bug
such that you can't simultaneously bind to the wildcard IPv4 and IPv6
addresses. That is, the following fails:

perdition --bind_address 0.0.0.0,'[::]'

Even though you may expect that is actually the default behaviour.

I'll look into resolving these problems.

In the mean I suggest using --bind_address to specify the
specific IPv4 and IPv6 addresses to bind to. You can have
more than once of each.

e.g.

./perdition/perdition --bind_address 10.4.3.135,[2001:3e0:a5f:403:7051:7bff:fe70:9724],[2001:3e0:a5f:403:a6ba:dbff:fefe:59fa]
