Export DNS Records to Zone File

The DNS records in the "Example DNS Check" record group are shown below in zone file syntax. This syntax can be imported into many DNS servers, like BIND, and DNS hosting providers.

Depending on what records are in this DNS record group and how your DNS service is configured, you may need to post different DNS records to different locations.

To learn more about this export format and how to import a zone file, see the Zone Files guide.

Forward DNS Records

We define "forward DNS records" as DNS records of any type other than PTR (reverse DNS). Examples of forward DNS records include A, MX, and TXT records.

Forward DNS records are managed on the authoritative name server(s) for your domain.

Some of these records can't be expressed in standard zone file syntax, so they are listed at the end of this file as comments:

• Load balancer records hold several values and may use CIDR ranges.
• Wildcard-value records match any value rather than a specific one.
• ALIAS records are not a standard record type with a documented zone file syntax.

Standard DNS servers ignore these comments, so the file stays fully compatible, and you can import it back into DNS Check to restore them.

Reverse DNS Records

Your hosting provider or ISP typically manages Reverse DNS (PTR) records.
