Hello- ARIN received the IPv4 address block 70.0.0.0/8 from the IANA on Jan. 15, 2004. In the near future, ARIN will begin making allocations from this new block. This will include allocations of /20 and shorter prefixes, according to ARIN's minimum allocation policy. You may wish to adjust any filters you have in place accordingly. For informational purposes, a list of ARIN's currently administered IP blocks can be found under "CIDR Blocks" at: http://www.arin.net/statistics/index.html Regards, Leslie Nobile Director, Registration Services American Registry for Internet Numbers (ARIN)
