BuddyNS is a free DNS delegation service that ensures your DNS remains accessible in the event that your primary DNS servers fail. BuddyNS provides:

  • fast and automated synchronization of your DNS records across BuddyNS
  • enhanced DNS security
  • low-latency DNS availability via a global cluster of servers
  • DNS troubleshooting tools

In general, BuddyNS is only necessary as well as usable for those who are running a VPS (“virtual private server”) or dedicated server for their web hosting. Those running low-cost “shared” web hosting generally have DNS provided by the web host.

BuddyNS also provides a free cPanel/WHM plugin that fully automates the synchronization of DNS zones.
