The reasons I have been told by enterprises regarding lack of IPv6 deployment boil down to 1) lack of business driver (i.e. does it make money?) and 2) many/most medium-large enterprises neither qualify for PI addressing nor would be able to multihome using PA addressing. Issue #2 is being worked on now, but until a policy is securely in place, an enterprise adopting IPv6 is giving up capabilities they have today with IPv4. > Are you indicating you believe that renumbering is > not an issue? Renumbering is not THE issue. Renumbering sucks. However, there are policies in place to make it so that renumbering doesn't have to happen too much. Also, once renumbering is at the "really unpleasant" point, that's when an organization generally qualifies for PI space. Renumbering IP space is no different than renumbering postal addresses - the time spent to do so varies directly with the size of the organization, but it doesn't have to be done often. BTW, the telephone analogy folks have been missing here is that of the 8xx system, where the numbers themselves are leased due to intrinsic value, and then redirected to a different inbound trunk/call center/whatever. The 8xx system is the one which maps to domain names, not the standard land-line system. Note that 8xx numbers are not purchased, they are leased, as they consume resources - if 1-800-FLOWERS didn't pay their bill for a while, their whole business would vanish. Perhaps a customer who wanted to make IP addresses "portable" would pay a fee to the ISP whose addresses they are, and maintain redirection equipment to the "real" IPs... And perhaps the price of doing so would actually be higher than just keeping a T1 to that first provider... -David David Barak Need Geek Rock?
