List of assigned /8 IPv4 address blocks
Appearance
Some large /8 blocks of IP addresses, the former Class A network blocks, are assigned in whole to single organizations or related groups of organizations, either by the Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA)[1], or a regional Internet registry.
Each /8 block contains 16777216 addresses.
As IPv4 address exhaustion has advanced to its final stages, some organizations, such as Stanford University, formerly using 36.0.0.0/8, have returned their allocated blocks to assist in the delay of the exhaustion date.
