ARIN's new allocations from IANA



ARIN received the IPv4 address blocks /8 and /8 and /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.
