and if everyone hands out /48's you just filter /48's. With a mix of /56 and /48 you need to filter at the /56 level. Given enterpises are getting /48's it will be simpler overall for everyone to get /48's.

=20 Give them a /48. This is IPv6 not IPv4. Take the IPv4 glasses off and put on the IPv6 glasses. Stop constraining your customers because you feel that it is a waste. It is not a waste!!!! It will also reduce the number of exceptions you need to process and make over all administration easier. =20 As for only two subnets, I expect lots of equipment to request prefixes in the future not just traditional routers. It will have descrete internal components which communicate using IPv6 and those components need to talk to each other and the world. In a IPv4 world they would be NAT'd. In a IPv6 world the router requests a prefix. =20 Mark =20 In message <495D0934DA46854A9CA758393724D5906DA244@NI-MAIL02.nii.ads>, = Erik Sun dberg writes: figure o=3D
