This is a FAQ.

Q: I keep getting log messages like the following. Why?

Dec 4 23:47:59 client 10.0.0.1#1355: updating zone 'example.com/IN': update
failed: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET)

A: DNS updates allow the update request to test to see if certain conditions are
met prior to proceeding with the update. The message above is saying that
conditions were not met and the update is not proceeding. See doc/rfc/
rfc2136.txt for more details on prerequisites.

Also prerequisites are processed before any acls according to RFC 2136 which
is why you see these even when updates are denied for everyone.
