Virtual DNS siphons off bad traffic from the good stuff.
The security vendor CloudFlare has launched a domain name service (DNS) proxy service for protecting websites from distributed-denial-of-service (DDoS) attacks.
Virtual DNS will stand between visitors and the DNS server, blocking any malicious traffic and masking the IP address of the name server, in order to save bandwidth and prevent the site from being disrupted or shutdown.
Dani Grant, an engineer at CloudFlare, said: "Many organisations have legacy DNS infrastructure that is difficult to change.
"The hosting industry is a key example of this. A host may have given thousands of clients a set of name servers but now realise that they don’t have the performance or defensibility that their clients need.
"Virtual DNS means that the host can get the benefits of a global, modern DNS infrastructure without having to contact every customer and get them to update their name servers."
The product launch follows testing with hosting providers, registrars and some enterprises, including cloud hosting providers DigitalOcean, which is now serving 10,000 requests a second, according to CloudFlare.
