Early registration addresses

remarks

------------------------------------------------------ Important: This range was initially allocated by InterNIC prior to the formation of Regional Internet Registries (RIRs). The early registration transfer project (ERX) transferred these blocks to be administered by each RIR based on the region in which the majority of resource holders resided. This early registration block has been transferred to APNIC's administration. However, not all of the resources under this block have been transferred to APNIC. For information on the Early Registration Transfer (ERX) project, see: http://www.apnic.net/db/erx
