[lacnog] IPv6 Transitional Uncertainties

[Raul Echeberria]

Dear Carlos:


It is not true that the other RIRs, as you said, are happy with the inequity in the allocations of IPv4 addresses. 
LACNIC has stated very clearly many times our position regarding legacy addresses, those addresses that were allocated before the existence of the RIRs.
In fact I spoke about that in the last LACNIC meeting in Cancun in my report. 

We can not do anything with regard to the addresses that are already allocated, but what we have claimed for is that those legacy address that are returned to an RIR or recovered by the RIR, should be made available for all the regions.

After a long discussion that has taken several years, it seems now that a global policy that establish a mechanism for IANA to manage a new pool of addresses, will be finally approved in ARIN region in october. At least I hope that. That policy has been already approved or is in the process of being approved in all the other regions, 

If the policy is approved as expected, LACNIC (and I believe that the other 3 RIRs have the same position) expect that ARIN Board commit to return to IANA any legacy space that is recovered or returned. 
The amount of IPv4 addresses that are already in that status is not very big, but it would give us the certainty that if more addresses are returned, those addresses will be passed to IANA for being allocated to all the RIRs. 

My disagreement with you in the recent meeting in Trinidad & Tobago was not about the principles, but about the facts and numbers that you mentioned there. 
The way in which you stated the problem was not exact in my view and so I tried to clarify the real nature of it. 

I am open to any further clarification or of course any discussion. 


What is very important from Geoff's article is that we have to learn the lessons from APNIC region's experience.  
in our region we have a good stock of IPv4 addresses to support a smooth transition to IPv6, but if the Network operators don't take the necessary measures very soon, so in a couple of years we will be in the same situation than APNIC region is now. 

It is a serious call to move forward as quick as possible. 

As Arturo has said, Geoff will be one of the keynote speakers at the next LACNIC and LACNOC meetings in Buenos Aires in the first week of October. I anticipate a very interesting presentation from him followed by a good discussion. 


Abrazos, 

Raúl
