Need DNS help
«

Hi,
I followed the tutorial on DNS Security to the letter and it just opened up a bunch of issues.
All I want is to have IPv4 and IPv6 available using DNSSEC. After I setup using the tutorial I had a bunch of DNS issues. Everything started resolving to IPv6 and then I had access issues. Outlook not working on the LAN. No access to Socks proxies. Seems all my IPv6 custom locations don't work because everything resolves to IPv6. I use static IP's from my ISP and they do not have IPv6 IP's available yet.
I don't know where to start. Is there a way to set overrides so certain domains are forced to resolve to IPv4? Or a way to always use IPv4, then use/fallback to IPv6 if no IPv4 DNS record exists?
As an example, if I tracert my email server domain, it returns an IPv6 address, but there is no IPv6 address on that server so I cannot get to it. Same with external proxies I access.
I did resort to disabling IPv6 on my NIC to access things, but I don't want all my users to have to do that. I do want to have access to IPv6 only sites. And I did set prefer IPv4 over IPv6.
Any help is appreciated.

Did you by any chance enable DNS64?

^This
If IPv4 domain are resolving with Ipv6 address you enabled DNS64, which you should NOT do unless you specify setup NAT64, which most people should not be doing.
