Vultr DNS supports creating subdomains through standard DNS record management for organizing and routing traffic to different services.
Subdomains are extensions of your primary domain that let you organize and route traffic to different services or servers, such as blog.example.com or api.example.com. Vultr DNS allows you to create subdomains by adding new DNS records. To set up a subdomain, create an A record using the desired subdomain name and point it to the IP address of the target instance.
For example, to direct blog.example.com to a specific Vultr instance, set the Name field to blog and enter the instance’s IPv4 address in the Data field. You can optionally update the TTL and Priority fields to control how long the record is cached and the order in which it is prioritized for certain record types. Once saved, the subdomain will resolve according to the configured record.
DNS propagation may take some time to complete, so it may not be immediately visible globally. To confirm that the subdomain is correctly pointing to your instance, you can run the following command:
$ dig blog.example.com +short
The expected output should display the IPv4 address of the Vultr instance you configured.
