Plus, 65% say they will have IPv6 running on their internal networks by then, too. One survey respondent, John Mann, a network architect at Monash University in Melbourne, Australia, said his organization has been making steady IPv6 progress since 2008. "Mostly IPv6 has just worked," he said. "The biggest problem is maintaining forward progress with IPv6 while it is still possible to take the easy option and fall back to IPv4.""
