A single instance of BIND can act as master for some zones,

I don't understand what you are trying to accomplish here...

Is the point simply to have two IP addresses responding to DNS lookups?
If so, then your "listen on" above has already done this, and your
server as master will respond on both IP addresses.

If you are trying to test something, and actually need to
configure both a master and slave on one physical server
(to make sure the config works or whatever),
then you would have to run two instances of bind, each listening
on a single IP address only.
