----- Forwarded message from Peter Hessler <phessler@xxxxxxxxxx> ----- Date: Thu, 23 Feb 2017 14:40:26 +0100 From: Peter Hessler <phessler@xxxxxxxxxx> To: ipv6@xxxxxxxx Subject: Objection to draft-ietf-6man-rfc4291bis-07.txt List-Id: "IPv6 Maintenance Working Group \(6man\)" <ipv6.ietf.org> Restricting all subnets to The One True Size(tm) of /64 is utterly ridiculous. Sure, that may be an artificial limitation of SLAAC and various other technologies, but *those* can have limitations. Limiting it inside the entire specification is even stupider of an idea than still supporting Classful networks. As an implementation, OpenBSD will never add such a crazy thing. And you know that many other implementations won't do so either. I strongly oppose this draft. -- Numeric stability is probably not all that important when you're guessing.
