; about SRV records
SRV (Service) records let DNS advertise where a specific service runs — including its host, port, priority, and weight. They follow the format _service._proto.domain.
Priority — lower = preferred. Clients try lowest first.
Weight — load-balance hint among equal-priority records.
Port — TCP/UDP port the service listens on.
Target — hostname of the server providing the service.
