A /60, /56, /52 or /48 allows the client to run multiple SLAAC subnets (16, 256, 4096 or 65536) and to have the reverse ip6.arpa zone delegated on a nibble boundary.Understood...There is plenty of address space even handing out /48's to everyone.Also Understood.Only short sighted ISP's hand out /56's to residential customers.I am curious as to why you say it is short sighted? what is the technical or otherwise any other reasoning for such statement ?
256 is *not* a big number of subnets. By restricting the number of subnets residences get you restrict what developers will design for. Subnets don't need to be scares resource. ISP's that default to /56 are making them a scares resource. Mark
