You are suggesting a policy change, but I'm unsure what you are
trying to accomplish in terms of a goal (and hence the text you
suggest may not be the most logical place to accomplish it.)
The anchor in NRPM 8.3 is the following text: "The recipient must
demonstrate the need for up to a 24-month supply of IP address
resources under current ARIN policies and sign an RSA."
I would generally recommend against putting a reference requiring
compliance to "need... under current ARIN policies" and then cutting
particular pieces of those policies out in subsequent statements
Note - we'll implement whatever is adopted, but doing so as you
suggest has a high risk of multiple interpretations and/or member
confusion when the try to decode the result.
If the intent is that their maximum transfer brings their total IPv4
holdings which meets their anticipated needs for IPv4 address space
for 24 months, then you might want to drop the current reference to
the allocation policy and simply state the intended maximum in plain
I do not know if I've addressed your question, and will note that
the elected ARIN AC excels at doing this sort of language (if you
want to submit a problem statement to the ARIN AC and work with
them on it...)
I hope this helps answer your question!
