> But they do reflect reality. If you look at the whole Internet, think there > are probably 1000 /64 links for every /65-126 link deployed today. 1000 /64 links for every /65-126 link may well be the case. However, plenty of non /64 links exist, and I see no sign of them going away. Claiming that all IIDs are 64 bit is simply incorrect, and doesn't reflect operational reality no matter how hard you try to make that claim. At least the ISP I work for will make sure (through RFP requirements etc) that /65-126 links *continue to work*. Steinar Haug, AS2116
