A /47 is larger than a /48, and under the draft must always be registered.
/48's are only registered upon request, or if it is independently routed.
/49 - /64 are only registered upon request. If future routing policy
changes allows these sizes to be independently routed and in fact are so
routed, they must also be registered. Currently, most networks will not
accept an advertisement smaller than a /48.
Smaller than /64 should never be assigned, and are never registered. Arin
policy 2.15 recommends each end site be given a /48.
The main difference from previous drafts is the part allowing the
downstream to require registration of their assignment. Currently this is
LIR's include the term ISP. See 2.4.
