DNS Service versions

The Cloud DNS Service version defines the contract and build information for the API.

Contract version

The contract version denotes the data model and behavior that the API supports. The requested contract version is included in all request URLs. Different contract versions of the API may be available at any given time and are not guaranteed to be compatible with one another.

Example: Request URL (contract version is 1.0)

API version headers
