 I would like to disagree with you, that Binkd keeps on trying a IPv4
 connection if only an IPv6 address is available.

 Moreover, Binkd has no knowledge of the Nodelist. It is the task of the
 intermediate software, that converts te Nodelist to Binkd's version to
 translate the INO4 to a "-6", or to exclude the node if the list is
 prepared for a ipv4 only node.
