You don't have to restart it. "rndc reconfig" will re-check the IPs on 
the machine and re-listen.

No. This has come up before - the bind listen-on statement is an ACL 
which is matched against the list of IPs on the box, not a list of IPs 
passed to the bind() syscall. There are various solutions, but "rndc 
reconfig" is the right one IMO.
