What is the address range for administratively scoped multicast addresses?

Administratively scoped multicast addresses are specifically defined within the address range of 239.0.0.0 to 239.255.255.255. This range is reserved for local use and is not routable on the Internet, allowing organizations to utilize multicast addressing for their internal networks without the risk of conflicts with globally scoped addresses.

This range allows for multicast communication among local groups or applications without interference from external multicast traffic, as the addresses are treated as local to a specific network or organization. The use of administratively scoped addresses is particularly useful in scenarios such as video streaming or conferencing within a corporate environment, where multicast traffic is needed for efficient distribution.

Other options refer to different types of address ranges. For instance, the range starting with 192.168.x.x is designated for private networks, while 224.0.0.0 to 239.255.255.255 encompasses globally scoped multicast addresses, which can travel across the internet. The address range of 233.0.0.0 to 233.255.255.255 is allocated for GLOP addressing, which is specifically for multicast addressing tied to an autonomous system number. Hence, option C correctly identifies the range for administratively scoped multicast addresses.
