[arin-ppml] Draft Policy ARIN-2015-10: Minimum IPv6 Assignments

[Mike Hammett]

Is this policy codifying that a /56 is the minimum acceptable assignment to an end-user and that if I assign less, I'm not allowed to come back to the IPv6 tough until I've filled up my space with whatever smaller than /56 allocations I decide to make? Not saying right or wrong, just seeking clarification. 

Maybe it's more appropriate under a different group than policy, but I'm new here, so this is the best spot I've seen so far (other than maybe ARIN-2015-1). Anything about X-Small ISPs and initial IPv6 allocations for them in the works? I know of many ISPs (personally, I know of dozens, though I'm sure several hundred of them exist in NA) that are X-small under IPv4 and don't have any IPv6 due to the added expense of moving up to small. yeah, it's not a large sum of money, but with increasing regulatory and network burdens, "bonus" areas like IPv6 are cast aside. Smaller blocks, smaller fees, I dunno, I'll let someone else figure out what's best there. Just trying to find ways of getting the little guys represented and brought into IPv6.

Draft Policy ARIN-2015-10 
Minimum IPv6 Assignments 

Date: 23 September 2015 

Problem Statement: 

ISPs may believe that they have an incentive to obtain smaller blocks 
than they really need, and once they receive their allocation may 
subsequently issue blocks smaller than their customers may need in the 
future. This policy seeks to encourage the correct behavior by 
reiterating the smallest reasonable sub-allocation size and by 
discounting any space which has been subdivided more finely from any 
future utilization analysis. 

Policy statement: 

Modify section 2.15 from "When applied to IPv6 policies, the term 
"provider assignment unit" shall mean the prefix of the smallest block a 
given ISP assigns to end sites (recommended /48)." to "When applied to 
IPv6 policies, the term "provider assignment unit" shall mean the prefix 
of the smallest block a given ISP assigns to end sites. A /48 is 
recommended as this smallest block size. In no case shall a provider 
assignment unit for the purpose of this policy be smaller than /56." 

Modify section 2.16.1 from "A provider assignment unit shall be 
considered fully utilized when it is assigned to an end-site" to "A 
provider assignment unit shall be considered fully utilized when it is 
assigned in full (or as part of a larger aggregate) to a single 
end-site. If a provider assignment unit (which shall be no smaller than 
/56) is split and assigned to multiple end-sites that entire provider 
assignment unit shall be considered NOT utilized."
