9.8 The Life of a Parent

That's a lot of parental advice to digest in one sitting, so let's recap the highlights of what we've talked about. The life cycle of a typical parent goes something like this:

1. You have a single zone, with all of your hosts in that zone.

2. You break your zone into a number of subdomains, some of them in the same zone as the parent, if necessary. You provide CNAME records in the parent zone for well-known hosts that have moved into subdomains.

3. After a grace period, you delete any remaining CNAME records.

4. You handle subdomain delegation updates, either manually or by using stubs, and periodically check delegation.

Okay, now that you know all there is to parenting, let's go on to talk about more advanced name server features. You may need some of these tools to keep those kids in line.
