The expiration, retry and refresh interval usually is based on the zone
data, but that's strange.

That is also strange that 192.112.36.4 would respond to a query originally
sent to 192.228.79.201. Ian, do me a favor and set a forwarder and let me
know what happens. Usually in most cases we recommend forwarding for a
number of reasons, main one is to offload the recursion processing to
another server. I usually mention to use 4.2.2.2, or you can use whatever
you like that supports the RA bit.
