As an alternative to adding individual zones manually, you have the option to import zone files from your previous DNS provider.
To import a zone file:
Download the zone file from your existing DNS provider.NOTE
Refer to this Wikipedia article to understand common and accepted zone file types.
In the NS1 portal, click Zones in the main navigation.
Click Add Zone.
Under Zone Settings, select the radio button next to Zone file import, and click Browse Files.
Navigate to and select the zone file , and click Open.
Click Save Zone. The new zone appears in the list with all associated records automatically created for you.
Zone files only capture static DNS records, so you'll need to configure Filter Chains for any dynamic and intelligent records manually.
If you experience issues when attempting to upload zone files, use the
named-checkzone tool to validate your zone file before uploading. If your file passes validation and you are still experiencing issues, contact NS1 support by submitting a support ticket or emailing email@example.com.
