How many bytes are there in an IPv4 address?

An IPv4 address consists of 32 bits, which are grouped into four octets. Each octet represents 8 bits, and since there are four of these octets in an IPv4 address, the total number of bytes is 4. This means that each octet (8 bits) corresponds to one byte, leading to a total of four bytes for the complete IPv4 address.

IPv4 addresses are typically expressed in a dotted-decimal format, such as 192.168.1.1, where each of the four numeric segments (0-255) corresponds to one octet (and hence one byte) of the address. Understanding this structure is fundamental in networking, as it helps in configuring devices, troubleshooting network issues, and comprehending how data is routed across the internet.
