ipv4 address exhaustion





























ipv4 address exhaustion is the depletion of the pool of unallocated ipv4 addresses. because there are fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s, when the internet started to experience dramatic growth. this depletion is one of the reasons for the development and deployment of its successor protocol, ipv6. currently ipv4 and ipv6 coexist in the internet.
ipv4 address exhaustion
an ipv4 address has a size of 32 bits, which limits the address space to (2) addresses. of this number, some addresses are reserved for special purposes such as private networks (~18 million addresses) and multicast addressing (~270 million addresses).





























ipv4 addresses are usually represented in dot-decimal notation, consisting of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., . each part represents a group of 8 bits (an octet) of the address. in some cases of technical writing, ipv4 addresses may be presented in various hexadecimal, octal, or binary representations.
