I have been similars problems when i add or delete some IP aliases in the same NIC that the daemon bind.
There are some very simple problems there (not security related). One: named binds to specific interfaces; if you remove and re-add the aliases, it never re-scans the interfaces, so any queries on said interfaces are not seen. yes, adding a new i/f to a nameserver blows away hundreds of megs of data. don't run an IP-based-virtual-server on a nameserver. :-) Two: named chooses, unless specified in named.conf, a random interface to source queries from. so if you add an IP alias in advance of moving some zones around when merging servers, you have to either have forced the interfaces used in named.conf for transfer-source and query-source or move the routing of the IP address you're moving across straight away to the new nameserver.
