  • Currenctly supported registrar modules: ISPAPI and RRPproxy
  • Define a global zone, to be applied to all new domain registrations
  • Define zones for specific hosting products, to be applied when registering a domain belonging to a hosting product
  • Supports A, AAAA, MX, MXE, CNAME, TXT and SRV records
  • Supports WHMCS specific URL and FRAME record types for the website redirection feature


  • WHMCS version 8.0 or higher For the latest WHMCS minimum system requirements, please refer to WHMCS System Requirements page.
  • PHP 7.4 or higher
  • One of the following registrar modules installed and enabled:
