Our Windows-based services authoritative DNS servers use Technitium DNS, an open source DNS solution. Our Linux-based (cPanel) services authoritative DNS servers use PowerDNS. Within our primary facility (Denver, CO), our internal resolvers also use Technitium DNS and provide standard DNS support as well as DoH, DoT, and DoQ support for privacy. Also supports security features such as QNAME randomization, QNAME minimization, and NS revalidation.
