Yes, the largest (or most surprising) difference is that with 411 a human
who receives a "wrong number" will find another "info" service and keep
trying whereas DNS clients who receive a wrong answer, use that whether
it works or not, and when receiving "no answer found" skip all other DNS
servers (even though they might move on to other resolution methods, e.g.,
NetBIOS.)
