I have seen a number of versions of that in reading things people sent me and things I found myself, and all of them seem to depend on ASICs that didn't exist at the time the ranges were chosen, and probably also CIDR which also didn't exist. They sound good, but I'm not buying em. :-)
Can't speak t the ASICs, but CIDR existed, even if your vendor was behind the times and still calling stuff class A/B/C. (Such nonsense persisted well into this century). Check the dates... [snip]
To be fair, the actual formal allocation was 1994 with rfc1597. 1918 was the reconciliation of 1597 and 1627 (ISTR the division was also why we saw 1796 and 1814). The practice had been used for a while before the codification but I don't have a good citation. IAB minutes of 1992 speak of the practice and the tut-tutting of not wanting people to do it, but not citing specific numbers and math. Cheers!
