Looking forward, Liu said that only organizations with a specific need for open recursive DNS servers -- and the technical ability to keep them from being flooded -- should run them.

"I would love to see the percentage of open recursive servers go down, because even if they're patched they make great amplifiers for denial-of-service attacks," he said. "We can't get rid of recursive servers, but you don't have to allow just anyone to use them."
