I've looked at this patch and compared it with the KDC.  I think both
are wrong.  Shouldn't we bind to 0.0.0.0 (only) unless we have bind
interfaces only, then bind to each interface (but not to broadcast)?

The challenge is is that we started this pattern by copying the NBT
server, which is not a good example due to the broadcast packet handling
requirement.
