Apologies for duplicate messages. ARIN will begin allocating IP address space from 74.0.0.0 /8 and 75.0.0.0 /8 within the next 2 weeks. ARIN was issued 74 /8, 75 /8, and 76 /8 by the IANA on June 17, 2005. Connectivity testing is currently being done by Team Cymru on the following three /20s (one from each /8). All of these test allocations originate with AS36666. 74.63.0.0/20 75.127.0.0/20 76.191.0.0/20 This is a reminder message that you may need to adjust any filters you have in place for these three blocks accordingly.
