I do not see real problems with the protocol, but mainly how it's used (and how it's advocated to solve some problems like privacy). If ISP's assign /48 prefixes to homes, those will be trackable. RIR's also have expressed a requirement to have contact information etc. for every prefix in the WHOIS database. > >From [EMAIL PROTECTED] Thu Aug 29 15:32:53 2002 > X-Authentication-Warning: sunroof.eng.sun.com: majordomo set sender to >[EMAIL PROTECTED] using -f > Date: Thu, 29 Aug 2002 22:27:30 +0300 (EEST) > From: Pekka Savola <[EMAIL PROTECTED]> > To: Thomas Narten <[EMAIL PROTECTED]> > cc: Steve Deering <[EMAIL PROTECTED]>, Joe Baptista <[EMAIL PROTECTED]>, > <[EMAIL PROTECTED]> > Subject: Re: IPv6 Interview Questions and critic > In-Reply-To: <[EMAIL PROTECTED]> > MIME-Version: 1.0 > Content-Type: TEXT/PLAIN; charset=US-ASCII > Sender: [EMAIL PROTECTED] > Precedence: bulk > > On Thu, 29 Aug 2002, Thomas Narten wrote: > > > Only parts of "this issue" were properly fixed.
