Interesting... I have a "normal household". I lack 2.5 kids and have no dog or cat. I have my own ARIN assignment. Are you saying that the 2.5 kids and the dog/cat would disqualify them? I can't find such a statement in ARIN policy. Are you saying that a household that multihomes is abnormal? Perhaps today, but, not necessarily so in the future. > 2) if their router goes down they loose network connectivity on the > same subnet due to loosing their ISP assigned prefix. > I keep hearing this myth, and I really do not understand where it comes from. If they get a static prefix from their ISP and configure it into their router and/or other equipment, it does not go away when they loose their router.

If IPv4 had contained enough addresses we probably wouldn't have always-on dynamic connections in the first place. Owen
