DNS is a hierarchical distributed database that lets you store IP addresses and other data and look them up by name. Cloud DNS lets you publish your zones and records in DNS without the burden of managing your own DNS servers and software.
Cloud DNS offers both public zones and private managed DNS zones. A public zone is visible to the public internet, while a private zone is visible only from one or more Virtual Private Cloud (VPC) networks that you specify. For detailed information about zones, see
Cloud DNS supports Identity and Access Management (IAM) permissions at the project level and individual DNS zone level. For information about how to set individual resource IAM permissions, see
