Hello- ARIN began allocating IP address space from 72.0.0.0/8 on Sept 10, 2004. We anticipate that we will be making allocations from 71.0.0.0/8 in the near future. These 2 IP address blocks were issued to ARIN by the IANA on Aug. 2, 2004. This is a reminder message that you may need to adjust any filters you have in place for these two blocks 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)
