>>> - a /48 in most cases >>> - a /64 if it is known that there will only be one subnet >>> (basically following the IAB recommendation) >> i suspect the 'most cases' is the /64, a single exchange mesh, and that >> the multiple interconnected meshes, which whould need the /48, is a rare >> case. > Well, I'd think it's more the case that a /64 is "single now, and > never plans to need more" and /48 is "likely to need some more in > future", thus shifting "most cases" towards /48. i think of an ix as more like an isp than an end user enterprise. we are careful to allocate to isps based on reality, not hallucinations from the marketing department. randy
