IPv4 addresses are 32 bits long.

Explanation:
IPv4 addressing uses 32 bits, which provides 2^32 possible addresses. Those 32 bits are divided into four 8-bit octets and typically written in dotted decimal notation like 192.168.0.1, with each octet ranging from 0 to 255. This fixed length enables subnetting through masks to separate the network and host portions of an address. Because there are about 4.29 billion possible IPv4 addresses, designers eventually faced exhaustion, leading to techniques like NAT and the move to IPv6, which uses 128-bit addresses for a vastly larger address space. So the statement is correct: IPv4 addresses are 32 bits long.
