Turning on a secondary Interface

[Kevin Darcy]

named will listen on all available interfaces that it can find, however it
only checks periodically whether interfaces have appeared or disappeared.
This scanning interval is controlled by the "interface-interval" option.

I think you can poke named to re-scan interfaces using rndc's "reload" or
"reconfig" commands. Worse come to worst, you could restart the nameserver
and then it'll scan when it comes back up.
