IPv6 came a step closer as ICANN added IPv6 host records to the root DNS servers, reports the BBC. 'Paul Twomey, president of Icann which oversees the addressing system, told the BBC News website there was a need to start moving to IPv6. "There's pressure for people to make the conversion to IPv6," he said. "We're pushing this as a major issue." The reason for the urgency, he said, was because the unallocated addresses from the total of 4,294,967,296 possible with IPv4 was rapidly running out. "We're down to 14% of the unallocated addresses out of the whole pool for version 4," he said. Projections suggest that this unallocated pool will run out by 2011 at the latest.'"
