  • DNS resolution
  • Cloud DNS
  • DNS Security (DNSSEC)

DNS resolution

VPCs come with internal DNS services. Machines get their internal names registered automatically within an internal zone. This allows VMs within the same network to access each other using the internal DNS names. The DNS record follows the life cycle of the VM. It's created when the VM is created and is deleted when the VM is deleted. This means that names are created when the instance is deployed and are removed when the instance is deleted. Note that the records are only created for internal IPs (not external and alias IPs). The resolution only works for VMs within the same VPC.

As you probably know, there are many types of DNS records (A, MX, SRV, CNAME, and so on). The actual records that are created in this case are...
