The reasoning behind /124 (rather than e.g. /127) for us, is simply to make addressing more "human-readable" as well as simpler to manage in terms of reverse DNS. Using /124 you always end up on a "human-friendly" boundary so your networks are xx::10/124, xx::20/124, xx::30/124 and so on, and you can then assign hosts that are always like xx::10:1/124 + xx::10:2/124 (rather than having your tech staff trying to sort out hexadecimal stuff in their heads). This also fits very nicely with nibble addressing in ip6.arpa as every network is its own "nibble". I believe someone wrote an I-D about using /124s a while back, but my memory isn't what it used to be...
Correcting myself here (not enough coffee yet) - the host addresses should of course be xx::11/124 and xx::12/124 and so on in the text above. :) Regards, Lars Erik
