samba - Sep 2016 - Samba DNS Listening IP

Is it possible to change the DNS listening IP?

I'd like to run a dnscache service for primary LAN queries, but the only
way to do this with Samba seems to be iptables preroute configuration to
redirect port 53 requests.

Thanks,

Just run Bind9 and use this as the Samba dns server instead:

I was leaning this way, but wanted to make sure there wasn't a way to do
this with the built in DNS.

Thanks,
