Obviously something wring with IPv6
20 years later and we are still struggling to gain widespread adoption. It’s looking a bit like DAB.
IPv6 has some major flaws, some of which have been addressed over the years, like the massive privacy fail we would have been exposed to by simply using the MAC address as the most significant bits of the address, would have permitted trivial tracking across internet connections. In IPv6’s inception it wasn’t a problem and IPv4 never had that problem.
IPv4 is mature, has loads of tools available, is well understood and has lots of security tools we can bolt on around it.
IPv6 is still immature due to its lack of use and lack of attention by hackers etc. While IPv4 has a lot of tools with skilled knowledgeable admins to secure it, IPv6 may have the tools but lacks the skilled knowledgeable admins.
After 20 years, we should be asking what we would design now and also ensure it would be backwards compatible to IPv4. Its not too late to redesign and come up with IPv8.
Biting the hand that feeds IT
