Announcing Virtual DNS: DDoS Mitigation and Global Distribution for DNS Traffic

On March 10, 2015, CloudFlare introduced Virtual DNS, a service that leverages its global DNS and proxying infrastructure to provide performance and security for any nameserver by acting as authoritative for its domains. The service helps protect against Distributed Denial of Service (DDoS) attacks on providers' nameservers, which can take down hundreds of thousands or millions of websites depending on those nameservers. Virtual DNS also offers two additional layers of security through the CloudFlare proxy: caching records at the edge for faster response times and masking the true origin IP addresses of the provider's nameservers to protect them from being targeted by attackers.
