    Query Options

    • Query restrictions: Specifies which hosts or IP addresses are allowed to send queries to this resolver.

    • Update restrictions: Controls updates to the DNS server, allowing you to restrict updates based on IP addresses or hosts to ensure authorized hosts make changes to your DNS records.
