It does not matter here.  There may and may not be other programs, dnsmasq 
or not, listening on 53 port on different interfaces.

not if you configure it only to listen on specific interfaces.
Without --bind-interfaces dnsmasq sits on 0.0.0.0 but only answers on 
interfaces it is configured to listen on.

this is the standard dnsmasq behaviour when new interface appears and you 
don't specify --bind-dynamic to detect them.
