great article that highlights the problems with ipv6, that sadly is somehow shoved under the rug.
I've spent countless of slepless night trying to mitigate DoS over ipv6 - since it is really great for DoSing stuff because a ipv6 package is approx 4x larger than a ipv4 one.
And I am not a fan of giving all the devices on the network a public ipv6 address either...
That is basically the reason I prefer not using it in critical environments.
