So in other words IPv4's shorter addresses didn't help at all? And also it seems like a lot to sacrifice in order to make something marginally more helpful about once or twice a year. Also why would you say it over the phone? Would you not ask them to email or IM it? I can't count the number of times passwords and names have been misunderstood over the phone. Numbers? Basically always at least one number is misheard.
