Reading the section on delegation in the O'Reilly book, I'm confused about<br>
something: The parent is configured to delegate the subdomain to the child<br>
with glue records, etc. But how does the child know who to ask if a host in<br>
the subdomain requests a record in the parent zone? They don't show any<br>
configuration example for that other than making the child a slave for the<br>
parent zone.<br>
