IPv4 and IPv6 subnets are different. While a single IPv4 is taken to be a single device, an IPv6 /64 is designed to be treated as an end user subnet. https://tools.ietf.org/html/rfc3177 section 3. On 05/04/2015 9:05 am, "Mike Hammett" <nanog () ics-il net> wrote:
That makes sense. I do recall now reading about having that 8 bit separation between tiers of networks. However, in an IX everyone is supposed to be able to talk to everyone else. Traditionally (AFAIK), it's all been on the same subnet. At least the ones I've been involved with have been single subnets, but that's v4 too. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original Message ----- From: "Valdis Kletnieks" <Valdis.Kletnieks () vt edu> To: "Mike Hammett" <nanog () ics-il net> Cc: "NANOG" <nanog () nanog org> Sent: Saturday, April 4, 2015 5:49:37 PM Subject: Re: Small IX IP Blocks On Sat, 04 Apr 2015 16:06:02 -0500, Mike Hammett said:I am starting up a small IX. The thought process was a /24 for every IX location (there will be multiple of them geographically disparate), eventhoughwe nqever expected anywhere near that many on a given fabric. Then okay,how do < we d o v6? We got a /48, so the thought was a /64 for each. You probably want a /56 for each so you can hand a /64 to each customner. That way, customer isolation becomes easy because it's a routing problem. If customers share a subnet, it gets a little harder....
