Chapter 9. Parenting > The Life of a Parent

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.
