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.
