I'm assuming you're being facetious. Those features can be done with v4 and v6, using DHCP, IPSec, and ideally some other features. If v6 is going to come into widespread use on the net, it has to be in production somewhere. Firewalled corporate networks are as sterile an environment to unleash it as any. As it stands, NAT was just a hack to conserve address space, and now that there are 'functional' v6 implementations maybe it's time to start thinking of a strategy for deployment. The reason I was asking if a study was done was to find out if there was any good reason, beyond curiosity, to deploy v6 on private production networks. If not, how long should we expect to have to tolerate vendor hubris and bad hacks to get around depleted address space? -- batz Chief Reverse Engineer Superficial Intelligence Research Defective Technologies
