An IPv4 address consists of 64 bits.

Explanation:
IPv4 addresses are 32 bits long. They’re built from four octets, each 8 bits, shown in dotted decimal notation (for example, 192.168.0.1). Because each octet can range from 0 to 255, the total number of unique IPv4 addresses is 2^32, which is about 4.29 billion. We’re dealing with 32-bit addresses here, not 64. IPv6, on the other hand, uses 128 bits and is written in hexadecimal in eight groups. So the statement that an IPv4 address consists of 64 bits is not correct.
