Could you try disabling DDNS updates for a little while? Maybe you'll
get lucky (for a given value of luck) and find that the problem
continues happening even with DDNS updates disabled. Thus you will have
a reasonable idea that the issue is not related to DDNS updates.

I'm sure that you could do some networking magic to cause connections to
$AlternateIP port 53 to be re-routed to $DifferentIP $AlternatePort.
