Is there anyone here working in an ISP where IPv6 is deployed? We are starting to plan the roll-out IPv6 to mobile subscribers (phones) I am interesting in knowing the mask you use for the assignment; whether it is /64 or /128.
In RFC 3177, it says: 3. Address Delegation Recommendations
The IESG and the IAB recommend the allocations for the boundary between the public and the private topology to follow those general rules:
- /48 in the general case, except for very large subscribers. - /64 when it is known that one and only one subnet is needed by design. - /128 when it is absolutely known that one and only one device is connecting.
Basically a sole device will be connecting to the internet so I am wondering if this rule is follwed.

Phones, as in 3gpp? If so, each phone alway gets a /64, there is no choice. https://tools.ietf.org/html/rfc6459
