Subject: allow listening on IPv6
X-Git-Tag: rec-4.1.0-alpha1~80^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=201aac4ac841f0845b5525e7729559a91eba56fb;p=thirdparty%2Fpdns.git

allow listening on IPv6

In IPv6 only environments it is not possible to listen on IPv6 addresses
for the control port.
This change takes a look at the provided IP and changes the connection type
to the correct address family.
