Server 2012 R2 DNS - IPv6 NS being used instead of IPv4

Hello,

I am running into an odd issue. Currently, a domain provider has their DNS set up in such a way that their IPv4 records expire before their IPv6. When this happens, they try asking the IPv6 NS servers for the answers instead of renewing the missing IPv4. How do I get around this? We do not have IPv6 configured so I cannot use that.

Example:

client asks for record
server checks for record, they are expired
server checks the NS servers that are set for those record - the IPv4's are expired and gone, but the IPv6 records exist
server tries IPv6 and fails the lookup, since ipv6 is not configured
server returns SERVFAIL To the client

How do I get the DNS server to renew the IPv4 NS records instead of moving onto IPv6? I cannot seem to find a functioning override for this. I have tried ensuring it is only listening to IPv4, unchecked IPv6 in the NIC, set the registry edit for ipv4 over ipv6 priority and disabled the teredo tunnel.

    domain provider has their DNS set up.........

    For what service or purpose? Domain controllers should be using statically configured addressing.

    Hi,

    In IP settings you have to check the two options below in the IPv4 settings and uncheck them on IPv6 settings:
