- 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. Robert
