Overview

The PowerDNS open source DNS server software offers high performance with very low memory requirements. cPanel’s PowerDNS implementation reads DNS data from the BIND files and stores DNSSEC data in a SQLite database. This makes cPanel’s PowerDNS compatible with most of cPanel’s DNS Management tools.

Install PowerDNS

To install PowerDNS via WHM’s Nameserver Selection interface (WHM » Home » Service Configuration » Nameserver Selection), perform the following steps:

1. Navigate to WHM’s Nameserver Selection interface (WHM » Home » Service Configuration » Nameserver Selection).

2. Select PowerDNS.

3. Click Save.

PowerDNS version

To check your server’s PowerDNS version, run WHM API 1’s installed_versions function. The function’s output contains the powerdns return, which displays the server’s currently-installed PowerDNS version.

DNSSEC

PowerDNS allows you to use DNS Security Extension (DNSSEC) with your domains’ DNS records. DNSSEC adds a layer of security to your domains’ DNS records. DNSSEC uses digital signatures and cryptographic keys to validate the DNS responses’ authenticity. These digital signatures protect clients from various forms of attack, such as spoofing or a man-in-the-middle attack.

To enable DNSSEC, follow the directions in our Zone Editor documentation.

Troubleshoot PowerDNS

To troubleshoot PowerDNS further, check the /var/log/messages error log.
