Goal: Reduce the size of the IN-ADDR.ARPA zone file. This file will be reduced in size by only containing name servers for /8 networks. Completed Steps: Apr 2001 - Established relationships with 2 companies to provide independent server networks for all ARIN IN-ADDR zone files. Jun 2001 - Released a new IN-ADDR.ARPA zone file generator to correct existing erroneous data. Next Step: July 9, 2001 - ARIN will begin revising the IN-ADDR.ARPA zone for those direct /8 delegations to ARIN. These /8 zone files will be serviced by the two ARIN nameserver networks. These changes will not affect the performance of reverse lookup in any of the IPv4 Address space. Please direct any questions to inaddr@arin.net.
