Looking for this interface?
Note:
Your hosting provider can enable or disable this interface for resellers in WHM's Edit Reseller Nameservers and Privileges interface (WHM >> Home >> Resellers >> Edit Reseller Nameservers and Privileges).
Overview
This interface is useful if your BIND or PowerDNS configuration file is corrupt, or if duplicate nameserver configuration files cause DNS problems for your server.
Warning:
- Do not modify nameserver configuration files while this process runs.
- Only run this process (or the
/usr/local/cpanel/scripts/cleandnsscript) on servers that use BIND or PowerDNS nameservers. Do not run this process on servers that use any other nameserver. - cPanel & WHM does not support email services or editing DNS for temporary domains. cPanel & WHM does not support transfers, backups, or restores of accounts with temporary domains.
Perform a DNS cleanup
Warning:
Performing a DNS Cleanup will clean up your named config file and remove any duplicated entries. Do NOT edit any nameserver configuration files during the clean up.
- Log in to WHM.
- On the Tools menu on the left side of the interface, scroll down and select DNS Functions. When the DNS Functions list expands, select Perform a DNS Cleanup (WHM » Tools » DNS Functions » Perform a DNS Cleanup). You can also find this tool by typing “Perform a DNS Cleanup” in the search text box in the top left corner of the interface.
- Click Proceed to run the cleanup.
When the cleanup process finishes, you will see a summary of the number of cleaned zones.
