Thanks, much appreciated!<br>

While I've been less than enthusiastic on this list about iterative<br>
nameservers (recursive resolvers) doing RDATA syntax validation, doing<br>
such validation at the authoritative servers is less objectionable, and<br>
I fully support RDATA validation when done before records are added to<br>
the zone.<br>
<br>
Compile-time type checks sure beat runtime errors.<br>
