To: The entire IETF community Sub: Why do we need to go for 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? Dear Folks, I raised this issue couple of time 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 am thankful to Mr. Suresh Krishnan for all the queries that he had. I have shown that all the points that he had, can be solved with 64 bits address space (Please follow a copy of my last mail as an attachment with all the answers). I believe all the points that were mentioned in the requirement specification of IPv6 can be achieved with 64 bits address space as well. I would request all the people mainly those who have been working with IPv6 for long to come forward 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 address space (at least) 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. 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). 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. Thanks.
