"Utilization Rate" is another term that didn't really make the transition to IPv6 - along with "CIDR", among others.

There are huge great swaths of unused space in every IPV6 LAN I assign - and huge great swaths of /64 LANs that go unused in every Site Allocation I assign. If I put devices on one in a million IPv6 addresses in a LAN, i'd still have 18 quadrillion hosts....and one helluva MAC flood.....

A "Good Utilization" of IPv6 space might measure in the millionth of a percentile - how do you differentiate it from someone who's NOT using their space at all? When is 0.0000000001 != 0?

I don't think it's a dumb question at all. There are too many practical obstacles with getting a commitment to move to IPv6 (being legally binding, what if the company shifts strategy, enforcement, etc) that would preclude this as a requirement.

    HI all,

    I’m often told that there are no stupid questions… to that, I say,
    hold my beer :)

    With this discussion about IPv4 allocations, the waiting list, and
    migration to IPv6 (which, as I understand it, is still a
    priority), has there been any proposal or discussion about
    requiring IPv4 requesters to commit to IPv6 migration?

    I’m not thinking about 4.10, which addresses facilitating
    migration to IPv6 for those starting that process. I’m thinking
    about something akin to the utilisation rate clause, where
    allocations depend on actual/future promised usage. Not a
    proposal, just a background query.

    I searched the archives and haven’t found anything quite as
    specific as that, hence my question.

    One other observation. In the NRPM, it is written:
    - 4.2.1.3. Utilization Rate
    - 4.2.3.4.1. Utilization
    - 4.2.4.1. Utilization Percentage (80%)
    - 4.3.3. Utilization Rate
    - 4.3.6.1. Utilization Requirements for Additional Assignment

    4.2.1.3. is a *statement* and all the others are *requirements*.

    Should these be clarified as Utilisation Rate for the statement
    and Utilization Percentage (X %) for the requirement, or similar,
    i.e.,

    - 4.2.1.3. Utilization Rate
    - 4.2.3.4.1. Utilization Percentage (80%)
    - 4.2.4.1. Utilization Percentage (80%)
    - 4.3.3. Utilization Percentage (50%)
    - 4.3.6.1. Utilization Percentage (80%) Requirements for
    Additional Assignment ?

    Many thanks.
