What am I missing? Is it just the splitting on the sextet boundary that is an issue, or do people think people really need 64k subnets per household?
With /56 you are giving each residential customer: 256 subnets x 18,446,744,073,709,551,616 hosts per subnet. I would expect at least 95.0% of residential customers are using 1 subnet, and 99.9% are using less than 4. I can understand people complaining when some ISPs were deciding to only give out a /64, but even with new ideas, new protocols and new applications, do people really think residential customers will need more than 256 subnets? When such a magical new system is developed, and people start to want it, can't ISPs start new /48 delegations? Since DHCP-PD and their infrastructure will already be setup for /56, it may not be easy, but it shouldn't be that difficult. I know the saying "build it and they will come....", but seriously.... I'd rather ISPs stop discussing deploying IPv6, and start doing it... Verizon: "The upgrades will start in 2013 and the first phase will include Verizon FiOS customers who have a dynamic IP address.". I'm still waiting...(at least I have a 6in4 tunnel with he.net). ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-694-5669 -----Original Message----- From: NANOG [mailto:nanog-boun...@nanog.org] On Behalf Of Marco Teixeira Sent: Thursday, July 9, 2015 11:09 AM To: Harald Koch Cc: NANOG list Subject: Re: Dual stack IPv6 for IPv4 depletion Probably because he got good advise from his father :) On Thu, Jul 9, 2015 at 3:46 PM, Harald Koch <c...@pobox.com> wrote: > On 9 July 2015 at 09:11, Mike Hammett <na...@ics-il.net> wrote: > > > I think you're confusing very common for a tech guy and very common for > > the common man.
