[ipv6-wg] RE: [address-policy-wg] 2010-06 New Policy Proposal (Registration Requirements for IPv6 End User Assignments)

I have some questions about the proposal
Question 1:
Why was chosen for "SUB-ASSIGNED PA" and not for "SUB-ALLOCATED PA" or even "LIR-PARTITIONED PA", which according to my understanding would be more in line with the IPv4 world and the proposal states it "...is largely designed based on the current IPv4 practice..."?
Besides that, ASSIGNED PA is the 'lowest status' in the IPv4. Using the term SUB-ASSIGNED PA higher in the hierarchy than ASSIGNED PA in IPv6 world might only create confusion.

Question 2:
Also, when putting such an inetnum object on the RIPE database, would it require approval from the RIPE NCC if the (initial) sub-'assignment' exceeds a /48 (in relation with RIPE-481 chapter 5.4.2)?

Question 3:
In IPv4 world (and policy document) the purpose of registration is "... to ensure uniqueness and to support network operations." (RIPE-492 4.0)

I realise that this sentence is not in the RIPE-481 document, so maybe this is out of order/scope, but in creating a 'pool' possibility we explicitely choose to not register inetnum information on the End User level. Does this not make "support network operations" a lot harder?

Question 4:
In IPv4 world, there are also LIRs that use this idea (registering a pool of addresses from which assignments are made to a number of different End Users) . But an extra status has not been required: on approval from RIPE NCC the LIR registers an inetnum with status "ASSIGNED PA". Why would an extra status be required in IPv6 world?


With kind regards,

Hi Marco,

Sorry. Probably my fault.

>>>> The only issue I have is that it appears to mandate that all assignments makes from a SUB-ASSIGNED PA block are exactly the length specified.  This means that if the ISP has policies of, say,  /56 for most customers but /48 for some, while at the same time wanting to implement some form of per-PoP prefix aggregation, it means assigning multiple blocks per aggregation point, one per assignment size.

>> bla::1/48 -> assignment size /56 

After thinking about it, this seems to be the best solution.
