Final answer:
The non-routable multicast addresses include 'Node Local' and 'Link Local'. 'Site Local' addresses are outdated and replaced by Unique Local Addresses, whereas 'Organization Local' addresses are routable within a single organization.
Step-by-step explanation:
The multicast addresses that are non-routable are:
- Node Local
- Link Local
- Site Local
'Node Local' addresses are designed to be used within a single node, making them inherently non-routable. 'Link Local' addresses are used within a single link or interface and are not intended to be routed across multiple links or outside local subnets. 'Site Local' addresses were once intended to be used within a single site or organization, similar to private address ranges in IPv4, but they have been deprecated in favor of Unique Local Addresses (ULA) which can be routed within a site or organization. 'Organization Local' addresses, though scoped to an individual organization, are still routable across multiple subnets within that organization.
