IPv4 (Internet Protocol Version 4) uses a 32-bit address, divided into four 8-bit octets separated by dots (e.g., 192.168.1.1). This structure allows for approximately 4.3 billion unique IP addresses (2³²). IPv4 is the most widely used version of the Internet Protocol, although it is gradually being replaced by IPv6, which uses 128-bit addresses to provide a vastly larger address space.
IPv4 address consists of how many bits?
