Ralph, > Thomas - is there any way in which you can quantify "excessive"?
Whether "excessive" is an appropriate word to use is a judgement call. YMMV. But, the word "excessive" is literally the word I hear many people (especially in the RIR and operational community) use when talking about this issue. And I'll note, that even when the IETF went forward with 3177 originally, I think we'd have to say consensus was "rough". Thus, even within the IETF, some people thought /48 was excessive. > E.g., make some suppositions for an ISP: > * number of subscribers > * subscribers per aggregation point (CMTS for cable) > * length of prefix required for each aggregation point > * length of prefix to be assigned to an ISP based on the above What 3177bis is talking about is the size of the assignment to a single end site, e.g., a home, a business, etc. The above are more about issues internal to an ISP (or a very very large end site), and thus the above really relate more to the size of the RIR->LIR (ISP) allocation. I.e., a different issue.
