Yahoo Suggests Hack To Support Proposed IPv6 [computerworld.com]
Network engineers from Yahoo are pitching what they admit is a "really ugly hack" to the Internet's Domain Name System, but they say it is necessary for the popular Web content provider to support IPv6, the long-anticipated upgrade to the Internet's main communications protocol.Major 'Net players mulling IPv6 "whitelist"
Yahoo outlined its proposal for changes to DNS recursive name resolvers at a meeting of the Internet Engineering Task Force (IETF) held here this week.
Yahoo says it needs a major change to the DNS -- which matches IP addresses with corresponding domain names -- in order to provide IPv6 service without inadvertently cutting off access to hundreds of thousands of visitors. Under Yahoo's proposal, these visitors would continue accessing content via IPv4, the current version of the Internet Protocol.
"If you roll out IPv6, you will break 0.078% of users. That sounds negligible, but for Yahoo that's taking 470,000 users offline," says Igor Gashinsky, a senior network architect at Yahoo. Gashinsky presented Yahoo's DNS recursive name resolver proposal to the IETF's DNS Operations Working group.
