Those were the days, I can remember having a conversation with Pipex here in the UK circa 1994 where their account manager asked if a /24 would be enough for the 64k line I was connecting. His assured me that they recommended at least 2 and that 4 * /24s wouldn't be a problem. Considering I was plumbing connectivity using SCO and the TIS FWTK at the time, a /29 was overkill.
