What is cssgServiceDNSPrimary?
Reports the primary DNS server address handed to a subscriber when they log into this service. Because different services can point subscribers at entirely different DNS servers, this is part of how a walled-garden service can silently control which names a subscriber can resolve, independent of whatever DNS the subscriber's own device requested. A corporate-VPN service might show cssgServiceDNSPrimary as an internal resolver address, so logged-in subscribers can resolve internal hostnames that a public DNS server never would.
