In the IPv4 world, a multicast address is a class D IP address. And a class D IP address has its first octet in the range of 224 through 239. And in this video, we want to take a look at some classifications of IPv4 multicast addresses that lie within this range. Let's begin with a reserved link local address. In other words, it's going to be useful between routers on a subnet. This is often used to speak between routers. You see the range is 224.0.0.0 through 224.0.0.255. As a couple of examples of well-known IPv4 addresses we might see in this range, we have 224.0.0.5, and that is all OSPF-speaking routers, or 224.0.0.6. just OSPF-speaking routers that are a Dr. a designated router, or a BDR, a backup designated router. Most of the addresses in this range fall under the category of a Globally Scoped Address, an address that is allowed to be used globally on the public internet.
