"What customers need to do within their intrusion-prevention systems or within their firewalls is to explicitly look for IPv6 traffic and drop it,'' says Tim LeMaster, director of systems engineering for Juniper's Federal group.
So Juniper is advising to drop IPv6 traffic?! Interesting point of view from a network hardware vendor; I would expect such a vendor to say "You need IPv6. Buy my stuff that does IPv6".
Oh, wait: maybe the reasoning is this: "You need to drop IPv6. Buy my stuff that can drop IPv6.".
