Med: I added this to my local copy: The text above focuses on the specification part which explains the behavior for requesting IPv6-related PDP context(s). Understanding this behavior is important to avoid having broken IPv6 implementations in cellular devices.

Med: I updated the text as follows: OLD: If [RFC6106] is not supported, the cellular host SHOULD retrieve DNS information using stateless DHCPv6 [RFC3736]. NEW: If [RFC6106] is not supported, the cellular host SHOULD retrieve DNS information using stateless DHCPv6 [RFC3736]. Note stateless DHCPv6 is useful to retrieve other information than DNS. > >>> REQ#15: Is the rationale here that a device with IPv4v6 PDP >>> context will >>> get a DNS64 enabled resolver? >> >> Med: No. The point is the host has to enforce a procedure to >prefer native IPv6 connectivity. > >I think REQ#15 should be re-written. > >REQ#15: The cellular host SHOULD, when dual stacked, support means to >prefer native IPv6 connection when faced with possibility of >native IPv6, >NAT64 or NAT44 connection to the same destination. > >... or something to that effect. The find the current wording >confusing. Med: I updated the text as follows: OLD: REQ#15: The cellular host SHOULD support means to prefer native IPv6 connection over NAT64 devices or NAT44 when the cellular host gets dual stack connectivity. NEW: REQ#15: When the cellular host is dual stack connected, it SHOULD support means to prefer native IPv6 connection over NAT64 devices or NAT44. Better? > >>> REQ#17: Should not do DAD on the PDP context interface. In case of >>> tethering/hotspot, it needs to do DAD on the wifi/lan >interface, right? >> >> Med: Yes. > >Clarification in the text? Med: I updated the text as follows: OLD: REQ#17: The cellular host SHOULD NOT perform Duplicate Address Detection (DAD) for these Global IPv6 addresses (as the GGSN or PDN-GW must not configure any IPv6 addresses using the prefix allocated to the cellular host). NEW: REQ#17: The cellular host SHOULD NOT perform Duplicate Address Detection (DAD) for these Global IPv6 addresses (as the GGSN or PDN-GW must not configure any IPv6 addresses using the prefix allocated to the cellular host). Refer to Section 4 for DAD considerations on the LAN interface when the 3GPP connection is shared. Are you Ok with the new text?
