The Cloud DNS API differs somewhat from the BIND syntax.

@ symbol

You must replace instances of @ with the domain of the zone.

Unqualified names

Short names, like the @ symbol, must be replaced with the full domain name. For example, the CNAME record for www must be changed to www.example.com. in the requests to the Cloud DNS API.

Multiple rows for the same type of record

For example, say you have two MX resource records (type field) for example.com (name field) that each have a different priority value. With the Cloud DNS API, you will create both of these resource records as a single change. The name and type field form a unique key for the records in the Cloud DNS API.

$TTL default value

The BIND syntax allows you to define a default time-to-live ( TTL ) value that will be used if a resource record does not specify its own TTL value. In the Cloud DNS API, you must define a TTL value for each resource record set.

The migration documentation helps walk through how you can move from a BIND zone file to Cloud DNS using the command-line tool or with the help of a Python script .
