It's also an attack that the best defence against is to deploy v6
across your entire network. Any areas of your network that are v6
enabled may or may not be vulnerable depending on your
equipment/config, but v4-only equipment that has no idea about IPv6
will always be vulnerable.

how many networks are using that bug as an excuse for not deploying
v6? also how many of them are hiring new staff to replace the idiot
who told them that ignoring IPv6 would make the issue go away? :)
