Re: [squid-users] why is the UDP port for DNS queries kept "open"?

I am also curious about this.

If it's not possible to change this, is it possible to limit which
interface that the internal DNS resolver binds to? I've tried
udp_incoming_address, but it didn't prevent it from binding to all
interfaces.
