This isn't the type of scenario in which CARP is envisioned to solve. You are mixing metaphors.

As a technology useful to implement redundancy, it is more common to set up the same functionality on each CARP server such that service is always available from somewhere. Instead of using CARP to connect a DNS master to its slave (which by definition isn't a model of true redundancy, but rather as a limited backup...), CARP is better used to connect two servers which both act as masters or both act as slaves.

In fact, this is the model proposed by ai-danno (who visits this forum from time to time...) several versions ago for OpenBSD 4.2:

However, be forewarned that the information is dated. Such articles bordering on how-to's do not absolve readers from doing their homework. Study the manpages.
