Oh, don't get me wrong - I'm not going to give anyone a hard time for assigning /48 for households. I was asking only because I've spent some time recently on various v6 address plans and by default I'm assigning /56, so I'm just wondering if I'm missing anything and there is any good reason for assigning /48 (the only reason I can think of is 'one day that site might want to be multihomed...'). -- SY, Jen Linkova aka Furry
