This is a new one on me. I've looked through the admin doc and grep
-i'ed in the doc arm directory and all I can find is DNSsec validation,
which I can understand. Nor does Google turn anything up about any DNS
validation that I didn't know already.
What's meant by "DNS validation" in this context?
