WG] that is not a privacy consideration that is unique to this document, and as such I recommend that we stay away from it, as it just distracts from the main point by essentially asking for rolling /64 assignments or multiple /64s. We need to keep the scope of this document fairly tight. > >But 'sharing' these IPv6 addresses with some other devices (64share) has >more serious drawbacks, typically in the number of subnets - only one >subnet is possible. WG] I fully expect implementations of the type that this draft discusses to get by with bridging if they need to share a /64 such as for mobile device tethering. If they truly need multiple subnets, there is no way to get around supporting DHCP_PD with some sane configuration around sending and accepting hints for larger prefixes, because that doesn't work for SLACC either. That probably needs to be another document, with those specific use cases documented, because "always support multiple subnets" is a more significant request than "always support multiple addresses" Thanks, Wes Anything below this line has been added by my company’s mail server, I have no control over it. ----------- This E-mail and any of its attachments may contain Time Warner Cable proprietary information, which is privileged, confidential, or subject to copyright belonging to Time Warner Cable.
