IPv4 addresses #shorts

An IPv4 address consists of 32 bits, which are divided into 4 octets (or 8-bit binary numbers) of information.

The octets are separated by a decimal point and each octet contains 8 bits of information. Each bit can be either a 0 or a 1, giving a total of 4,294,967,296 possible unique addresses.

IPv4 addresses are used to identify and locate hosts on the Internet, and are assigned by a central numbering authority called the Internet Assigned Numbers Authority (IANA).
