Comcast is mostly an end-user ISP isn't it? Because in ARIN land ISPs are supposed to calculate with /56s and suddenly there is a lot of space for doling out /56 to end-users and /48s and larger for their corporate clients. And then it is good that they are skipping out on the 6rd deployment. Funny to see that even good network engineers did not grasp the concept of 'request a /48 for every customer', and multiply that with the HD ratio and voila request that address space and be over with it, but that they had to return for a second prefix though... Also https://www.arin.net/policy/nrpm.html --------------------- 2.8. Utilization (IPv6) In IPv6, "utilization" is only measured in terms of the bits to the left of the /56 boundary. In other words, utilization refers to the assignment of /56s to end sites, and not the number of addresses assigned within individual /56s at those end sites. ------------------ Although in 2.15 in that document it is recommended to do /48. Though this is not reflected in the current policy, it likely comes from 2005-8 (https://www.arin.net/policy/proposals/2005_8.html) 8<------- The following guidelines may be useful (but they are only guidelines): - /64 when it is known that one and only one subnet is needed - /56 for small sites, those expected to need only a few subnets over the next 5 years. - /48 for larger sites ---------->8 Greets, Jeroen
