An IPv4 address is comprised of how many binary bits?

An IPv4 address is 32 binary bits long. This comes from four octets of 8 bits each: 4 × 8 = 32. That 32-bit length defines the total number of possible addresses (2^32). In dotted decimal form, each octet ranges from 0 to 255, which reflects 8 bits per octet. The subnet mask can vary (such as /24 or /16), but it doesn’t change the address length itself. IPv6, by contrast, uses 128 bits. So the correct total is 32 bits.
