- A32 bits, written as four dotted decimal octets
- B64 bits, written as four dotted decimal octets
- C128 bits, written as four dotted decimal octets
- D16 bits, written as four dotted decimal octets
Why this is the answer
An IPv4 address is 32 bits, shown as four octets like 192.168.0.1. 128 bits is the size of an IPv6 address, not IPv4.
