To: The Entire IETF community Sub: Why do we need to go with 128 bits address space if whatever is been trying to achieve with the existing approach of IPv6, can be achieved by 64 bits address space as well? Dear Folks, I raised this issue couple of times earlier. My intention was to collect all the points in support of 128 bits address space and try to figure out whether they can be solved with 64 bits address space as well. I believe that all the points that were mentioned in the requirement specification of IPv6, can be achieved with 64 bits address space as well. I have received comments and queries from few people (including Suresh Krishnan, Robert Moskowitz, Fred Baker, Ted Lemon, Ole Troan, Jordi Palet, Mark Smith and Gyan Mishra) so far. I am thankful to all of them for all their inputs. I have tried to answer all the queries that they had (Please follow the attached file). I would request more and more people to come forward and deliver their inputs in favor of 128 bits address space that can not be achieved with 64 bits address space. If it can be shown that 64 bits address space is good enough to solve all the requirements, either we have to move back to 64 bits address space in the future or we have to carry through this extra burden for ever for no reason. I would request readers to go through draft-shyam-real-ip-framework as a reference. It shows that if address space gets assigned to customer networks based on their actual need (in contrast to 64 bits prefixes for any customer network in IPv6), 64 bits address space is good enough for this world. Along with that, it comes up with the following: 1. It shows how to make a transition from (NAT based) private IP space to (NAT free) real IP space. 2. It comes up with a light weight routing protocol applicable inside VLSM tree that satisfies all the features supported by BGP. (It is applicable in IPv6 environment as well with the required changes in the addressing architecture). 3. It come up with a simple protocol for Host Identification with Provider Independent Address with the approach of DNS. This can be considered as an alternative of existing protocol (HIP). (It is applicable in IPv6 environment as well with the required changes in the addressing architecture). 4. It comes up with a hierarchical distribution of network for the convenience of routing and distribution that may be considered as useful in the long run. Hence, I would request all the like minded people to come forward and look into this matter seriously. Last time I had sent this mail to the 105attendees list. Robert Moskowoitz suggested to move it to the IETF mailing list. Fred Baker suggested to send this as a proposal to the IRTF list. Hence, I am sending this mail once again. Thanks and regards, Shyam
