[AusNOG] RFC7278 - "Extending an IPv6 /64 Prefix from a Third Generation Partnership Project (3GPP) Mobile Interface to a LAN Link"

[Mark ZZZ Smith]

Hi,

The following recently published RFC might be of interest to people on this list.

RFC7278 - "Extending an IPv6 /64 Prefix from a Third Generation Partnership Project (3GPP) Mobile Interface to a LAN Link"

http://tools.ietf.org/html/rfc7278

Earlier versions of the 3GPP standards (i.e., basically mobile phone data standards) didn't recognise or realise that smartphones would also be able to temporarily become IP routers/Wifi hotspots, and therefore didn't specify DHCPv6-PD. This RFC describes how to take a /64 from the phone to carrier link and use it/share it with the phone's Wifi LAN interface when the phone is acting as an IPv6 router. It may seem a bit obscure, however it provides some examples of how IPv6's capabilities can be used to novelly overcome this limitation. It certainly isn't a recommendation to give a customer a single /64 rather than many of them (i.e., as per RFC6177, a /56, or better IMO, a /48 as per the considerations in RFC3177), but it does show how that can be worked around with some limitations.

Regards,
Mark.
