kdc listening on too many interfaces

Running Kerberos 5 release 1.6.3 on a new server - we have a backnet  
interface for Backups. When I start the kdc I see this in the logs:

Jun 07 00:21:59 afsdb0 krb5kdc[5761](info): setting up network...
Jun 07 00:21:59 afsdb0 krb5kdc[5761](info): skipping unrecognized

BackNetIPAddress.88
Jun 07 00:21:59 afsdb0 krb5kdc[5761](info): listening on fd 11: udp  
BackNetIPAddress.750

Everything works fine and in theory I see no harm but still it seems wrong.
It seems like I ought to be able to disable listening on the backnet  
interface.
Is this so or no?
Lots of Googling have so far revealed nothing.
