What is the multicast scope for FF0E in IPv6?

• A. Global
• B. Link-local
• C. Site-local
• D. Interface-local

Answer: (A)

In IPv6, the address range starting with FF0E indicates a specific multicast address that falls under the global scope. Multicast addresses in IPv6 are categorized into different scopes to specify their reach or the range within which they are valid and can be utilized. The global multicast scope means that these addresses can be routed across the entire internet, and any host on the internet can potentially send packets to this address. These addresses are used for applications or services that require communication with a potentially large group of recipients that are not restricted to a single local or site network. Understanding the different multicast scopes is important for network design and implementation, as it impacts how multicast traffic is managed and delivered throughout IPv6 networks. The other scopes, such as link-local or site-local, limit the multicast transmission to either the local segment of a network or a specific site, respectively, thus making them unsuitable for a global scope multicast address like FF0E.
