#### Managing Zones

Record sets in `gcloud-java-dns` are managed inside containers called "zones". `ZoneInfo` is a class
which encapsulates metadata that describe a zone in Google Cloud DNS. `Zone`, a subclass of `ZoneInfo`, adds service-related
functionality over `ZoneInfo`.

*Important: Zone names must be unique to the project. If you choose a zone name that already
exists within your project, you'll get a helpful error message telling you to choose another name. In the code below,
replace "my-unique-zone" with a unique zone name. See more about naming rules [here](https://cloud.google.com/dns/api/v1/managedZones#name).*

strings. The format of the strings depends on the type of the DNS record to be added.
