It s true. That s not the reason it is insecure. The reason it is insecure is people who infiltrated the committee made sure to make data exfiltration possible through mandatory ICMP for everything.

Good luck setting up proper firewallimg rules for IPv6 while both respecting its specs and preventing hard-to-detect exfil through ICMPv6.

It's a rube-goldberg of a protocol and it s hard to believe it s all incompetence and there ain't t some malice involved.

NAT for IPv4 was an accidental godsend, especially useful in an era where you d hack your neighbors' computers when they where on the same subnet as yours. Don t tell me it didn't t happen for I was doing that on dial-up back in the days.

Thankfully the point is mostly moot because people are still free to use IPv4 at home/companies while having their router using IPv6.

IPv4 shall thankfully outlive me. And I don't t care if it means more work for people working in the "punch the monkey" ads industry.
