How Many Bits are in an IPv4 Address?

Answer: The number of bits in an IPv4 address is 32 bits (or 4 Bytes).

The IPv4 address are of 32 bits or 4 Bytes. The IPv4 address is represented using dotted decimal format. The 32-bits of IPv4 address is divided into 4 parts of 8-bits as a.b.c.d where a, b, c and d are decimal numbers that can be denoted using 8-bits. These 32-bit represents the number of network as well as number of hosts in the given IPv4 address.

An IPv4 address consists number ranging from 0 to 255. This format allows for approximately 4.3 billion unique addresses. Due to the rapid growth of internet-connected devices, IPv4 addresses are becoming increasingly scarce, leading to the adoption of IPv6, which uses a 128-bit address space to accommodate a vastly larger number of unique addresses.
