named: how to disable ipv6 lookups on windows 10?

[Mark Andrews]

Use server clauses.  Most specific wins.

	server ::/0 { bogus yes; };		// all of IPv6
	server 2001:DB8::/48 { bogus no; };	// site

server <netprefix> {
        bogus <boolean>;
        edns <boolean>;
        edns-udp-size <integer>;
        edns-version <integer>;
        keys <server_key>;
        max-udp-size <integer>;
        notify-source ( <ipv4_address> | * ) [ port ( <integer> | * ) ] [
            dscp <integer> ];
        notify-source-v6 ( <ipv6_address> | * ) [ port ( <integer> | * ) ]
            [ dscp <integer> ];
        padding <integer>;
        provide-ixfr <boolean>;
        query-source ( ( [ address ] ( <ipv4_address> | * ) [ port (
            <integer> | * ) ] ) | ( [ [ address ] ( <ipv4_address> | * ) ]
            port ( <integer> | * ) ) ) [ dscp <integer> ];
        query-source-v6 ( ( [ address ] ( <ipv6_address> | * ) [ port (
            <integer> | * ) ] ) | ( [ [ address ] ( <ipv6_address> | * ) ]
            port ( <integer> | * ) ) ) [ dscp <integer> ];
        request-expire <boolean>;
        request-ixfr <boolean>;
        request-nsid <boolean>;
        request-sit <boolean>; // obsolete
        send-cookie <boolean>;
        support-ixfr <boolean>; // obsolete
        tcp-keepalive <boolean>;
        tcp-only <boolean>;
        transfer-format ( many-answers | one-answer );
        transfer-source ( <ipv4_address> | * ) [ port ( <integer> | * ) ] [
            dscp <integer> ];
        transfer-source-v6 ( <ipv6_address> | * ) [ port ( <integer> | * )
            ] [ dscp <integer> ];
        transfers <integer>;
}; // may occur multiple times
