Hello-

ARIN received the IPv4 address blocks 74.0.0.0 /8 and 75.0.0.0 /8 and 76.0.0.0 /8 from the IANA on June 17, 2005.  In the near future, ARIN will begin making allocations from these new blocks.  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:
