LX0-104 · Question #456
What are the addresses falling into the range of 224.0.0.0 through 254.0.0.0?
The correct answer is C. This is an experimental address range. The IPv4 address range from 224.0.0.0 through 254.0.0.0 includes multicast addresses and addresses officially designated as experimental or reserved for future use.

Why each option
The IPv4 address range from 224.0.0.0 through 254.0.0.0 includes multicast addresses and addresses officially designated as experimental or reserved for future use.
Class C networks range from 192.0.0.0 to 223.255.255.255, so the given range starts above Class C.
Class B networks range from 128.0.0.0 to 191.255.255.255, so the given range starts significantly above Class B.
The range 224.0.0.0 through 239.255.255.255 is assigned for Class D (multicast) addresses, while the range 240.0.0.0 through 255.255.255.255 is designated as Class E and reserved by IANA for experimental purposes or future use, not for general assignment or routing on the public internet.
While specific addresses within this range might be used in multicast contexts or for limited broadcast (255.255.255.255), the entire range itself is not classified as a 'broadcast range' in IP addressing.
