[arin-ppml] The non-deployment of IPv6

[John Curran]

Chris - 
 
  By "doing IPv6", do you mean for your internal network, desktops, and servers?  Or do you mean for your public-facing web and mail servers?

Furthermore the paradigm is sufficiently different that it's not like it's a seemless transition from v4. If they had just taken 4 and tacked on a few more octets but made no other changes as to how it worked, that might be a bit of a different story. No surprise that many Enterprises aren't rusing to adopt. The key question for an Enterprise Admin is do you have control over the hardware and networks on which the services you provide depend?  If the answer to that is ....yes.... then looking to switch to v6 really makes no sense.

I imagine that will be some variety of v4 to v6 gateway services or something like that. A few years down the road, if some-one is building a new network from the ground up I could see them maybe deciding to go v6 native. However, for existing networks...as long as there are robust v4 to v6 solutions available....and I imagine there will be due to demand.... I can't see any reason to switch away from v4 native for the forseeable future.
