Hoy to query by service name with endpoint_mode=dnsrr from host network

I'm configuring some databases in a swarm cluster environment to use endpoint-mode = dnsrr

Documentation says (https://docs.docker.com/network/overlay/):

"A DNS query for the service name on the Docker host returns a list of IP addresses for the nodes running the service"

I'm having trouble to understand what this sentence is saying.

If I use dig to query the service name, which dns server which I have to use?. Swarm manager (which I understand as docker host) is not running a DNS server as I know.

What I do know is that inside an overlay network you can resolve using tasks.$servicename, but for dnsrr and host network, how it is done?
