Cloud DNS

Cloud DNS is Google Cloud's managed, authoritative DNS service. It translates domain names into IP addresses with high availability, low latency, and a 100% uptime SLA. Cloud DNS supports both public zones (internet-facing) and private zones (internal to your VPC), making it the single DNS solution for all your GCP workloads.

What Is Cloud DNS?

Cloud DNS is a fully managed, authoritative DNS hosting service. You create DNS zones and records, and Google operates the global infrastructure to answer DNS queries. Key features:

• 100% SLA — Google guarantees 100% availability for authoritative DNS queries.
• Global anycast network — queries are answered from the nearest Google edge location.
• Scales automatically — handles millions of queries per second without provisioning.
• Supports all standard record types — A, AAAA, CNAME, MX, TXT, SRV, NS, SOA, CAA, and more.

Public Zones

A public zone hosts DNS records that are resolvable from the internet. When you register a domain (e.g. example.com), you create a public zone in Cloud DNS and update your domain registrar's nameservers to point to the Cloud DNS nameservers.
