But (particularly in an enterprise environment) less important than =
getting the end-user machines IPv6 enabled.
At least I haven't been convinced otherwise yet... yes, it's =
reasonable, but at least in my situation it'll probably be after all =
user facing segments are done.
Also, so far, all IPv6 content whitelisting has been done on the IPv4 =
address of nameservers... so really, no rush.
