Correct answer: D
Class E IP addresses are reserved for experimental and future use. In IPv4 addressing, the first few bits of an IP address determine its class. Class A addresses start with 0, Class B with 10, Class C with 110, and Class D (multicast) starts with 1110. Class E addresses are defined by the first four bits being 1111, which corresponds to the range from 240.0.0.0 to 255.255.255.255.",
