DNS records are instructions that define how your domain name works on the internet. They control things like where your website loads from, how your emails are routed, and which services can connect to your domain. They are essential for making sure everything linked to your domain functions correctly. Bolt gives you the ability to add and manage custom DNS records right in your Project Settings, so you can easily configure your domain to match your needs.

​
DNS Record types

Bolt supports the creation and management of the following types of records:
  • AAAA: IPv6 Address record, which is used to map host names to their IPv6 address.
  • CAA: Certificate Authority (CA) Authorization, which is used to specify which CAs are allowed to create certificates for a domain. If subdomains don’t have their own records, they inherit the same records from the apex domain.
  • CNAME: Canonical name record, which is used to specify alias names.
  • MX: Mail exchange record, which is used in routing requests to mail servers.
  • NS: Name server record, which delegates a DNS zone to an authoritative server. If subdomains don’t have their own records, they inherit the same records from the apex domain.
  • SRV: Service locator record, which is used by some voice over IP, instant messaging protocols, and other applications.
  • TXT: Text record, up to 255 characters. It can contain arbitrary text and can also be used to define machine-readable data, such as security or abuse prevention information.

​

Your DNS Records In addition to system records, you can create and manage your own DNS records in Domain Settings. These user records let you configure how your domain behaves.

Limitations on creating records

You cannot create an A or AAAA record for a domain/subdomain if a system DNS record already exists for that domain/subdomain. You cannot view system record details, but you will see an error message that lets you know if you’ve attempted to add a record that already exists. See the example screenshot below: The error message when adding a duplicate A record in DNS Records You also cannot create A, AAAA, or CNAME records for domains/subdomains that already have a user-created DNS record. In these situations, you should update the existing record or delete it and create a new one.
