How many bits and bytes are in an IPv4 address?

How many bits and bytes are in an IPv4 address?

• 128 bits (16 bytes)
• 64 bits (8 bytes)
• 256 bits (32 bytes)
• 32 bits (4 bytes) 

EXPLANATION

IP addresses in Internet Protocol version 4 (IPv4) networking consist of 32 bits (4 bytes).
The address 192.168.0.1, for instance, has values 192, 168, 0 and 1 for each of its bytes. The bits and bytes of that address are encoded like so:

11000000 10101000 00000000 00000001
