IPv6 will drive increased DNS queries
"As IPv6 preparedness and deployment continues, we anticipate considerable growth in IPv6 queries, both in absolute terms, and also as a ratio of aggregate queries," Kane said.
Kane added that while there are protocol and implementation complexities introduced that result in additional DNS system load during IPv4/IPv6 coexistence, VeriSign is confident that they're ahead of the curve in IPv6 transaction servicing capabilities.
"Over the past year alone, queries over IPv6 have nearly doubled as a ratio of aggregate queries, from about half a percent to nearly one percent of all transactions we service," Kane said.
"Anytime you add integrity and authentication capabilities to an information system some amount of overhead is incurred," Kane said. "In the case of DNSSEC, the tradeoff to allow Internet users to transact with more confidence and enable new applications is well justified."
Kane added that from a protocol mechanics perspective, DNSSEC does require more transactions and introduces new DNS record types, inherently placing more load on the system. He noted that VeriSign is ready for the additional demands of DNSSEC.
"In the past year alone, we've worked with the Internet community to enable DNSSEC at the root and the .net zone with no noticeable impact to Internet users, with .com being DNSSEC-enabled just on the horizon, and all while continuing to provide 100 percent uptime and availability for more than 12 years," Kane said.
