Question: 1 / 400

What range of IP addresses is designated as Multicast Administratively Scoped Block?

224.0.0.0 to 224.255.255.255

239.0.0.0 to 239.255.255.255

The range of IP addresses designated as the Multicast Administratively Scoped Block is 239.0.0.0 to 239.255.255.255. This range is specified in RFC 2365, which defines the administratively scoped multicast addresses similar to how private IP addresses function in IPv4 addressing. The intention behind this block is to allow organizations to use multicast within their own networks without affecting the global multicast address space.

Using this range, organizations can implement multicast communication for applications such as video conferencing, streaming media, and other group-oriented network services limited to internal network segments. It ensures that multicast traffic does not unintentionally propagate throughout the global internet, thus allowing better control of multicast traffic within local networks. This specificity makes it distinct and beneficial for managing multicast efficiently.
