Third Party DNS and A Records

I am using IP Extension, which IP address should I use in third party DNS; original or actual?

Hello,

You shall be able to use both actually, can you test and let us know?

When using IP Extension (like with an IPv6 network), you should use the actual IP address of the device in the third-party DNS configuration. This is the IP address that the device is currently using to communicate on the network, ae credit card and it's the address that the DNS server needs to be aware of to resolve domain names to this IP.
