The world launch of IPv6 happened back in June 2012, and World IPv6 Day was on Friday 8th June. But just how secure is IPv6 some six years after that fanfare deployment?

Development of IPv6 first started in the early 1990’s when it was realised that the physical limitation of 4.3 billion unique IP addresses in the IPv4 protocol wasn’t going to be enough to support Internet growth. And that was before the Internet of Things had even been thought about. IPv6 addresses the problem, if you’ll excuse the pun, by providing 340 trillion, trillion, trillion unique addresses.
