IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses. Because the original Internet architecture had fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s when the Internet started experiencing dramatic growth.
This means that 256 /8 address blocks fit into the entire IPv4 space. 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 (in this case to APNIC) to assist in the delay of the exhaustion date.

Since the introduction of the CIDR system, IANA has typically allocated address space in the size of /8 prefix blocks for IPv4 and /23 to/12 prefix blocks from the 2000::/3 IPv6 block to requesting regional registries as needed. Since the exhaustion of the Internet Protocol Version 4 address space, no further IPv4 address space is allocated by ...
It was designed in 1981 to address up to ≈4.3 billion (10 9) hosts. However, the explosive growth of the Internet has led to IPv4 address exhaustion, which entered its final stage in 2011, [78] when the global IPv4 address allocation pool was exhausted.
Internet Protocol version 4 (IPv4) was the first standalone specification for the IP address, and has been in use since 1983. [2] IPv4 addresses are defined as a 32-bit number, which became too small to provide enough addresses as the internet grew, leading to IPv4 address exhaustion over the 2010s.
