I still haven't seen any good argument for why residential users need /48s. No, I don't think "that makes all the address assignments the same size" is a particularly relevant or convincing argument. We're doing /56 for residential users, and have no plans to change this. Steinar Haug, Nethelp consulting, sth...@nethelp.no
