IPv6 address classification - unicast, multicast & anycast

hello and this is sunny welcome back today my topic is ipv6 address classification there are three types of ipv6 addresses unicast multicast and anycast like ipv4 classes a B NS a ipv6 unicast uses one-to-one association between two individual devices each unique has the destination address uniquely identifies a single receiver on a network unicast has several types for different purposes such as a local link unicast global unicast and several others I will talk about them in details in next video yipeee eally for a host needs a broadcast communication when it does not know the receivers address broadcast is ipv4 type of communications where's messages from a single sender can be heard by all other devices on the same broadcast network IP v6 there is no broadcast address or broadcast Adamic instead ipv6 uses multicast multicast is one remaining type of a communications ipv6 multicast addresses use the prefix F F 0 0 : : / 8 which is equivalent to the ipv4 multicast address 224 0 0 0 / for a packet sent it to the multicast group always have a unicast a source address a multicast address can never be source address I physics has many different types of multicast addresses for different purposes here I introduce two types multicast addresses only well-known multicast addresses and a so listed note addresses well know multicast addresses are reserved for predefined groups of devices such as all nose and all routers multicast groups ff0 to a calling calling wine is all nose address which means all nose identified by this address on the local network can get the messages FF 0 2 colon colon 2 is all routers address which means all routers on a local network segment can hear multicast messages with this address as the destination so listed in node addresses are automatically created by prepending the soleus to denote multicast are prefixed FF 0 to calling Holy One calling FF 0 0 calling 0 0 0 0 / 104 - the last 24 bits of the unicast or anycast address for example and if we have IP VCG unicast this IP address and is corresponding so listed node multicast address is look like this and you might notice the last 24 bits is the same a host is required to join the solicited node multicast group for each o is configured unicast or anycast addresses you may ask why a host needs so listed note address because it is a useful and necessary for link clear address resolution with a neighbor discovery protocol on the link without disturbing all notes on the local network I will introduce neighbor discovery protocol in a separate video the 30 type IP with six address classification is any caste any caste is one two nearest Association it is a typically used by routers and ipv6 anycast address is an address that can be assigned to a group of routers in other words multiple routers can have the same anycast address a packet sent to anycast address is a forward to the nearest router according to routing protocols the determination of the nearest router is calculated on the basis of the number of hops distance efficiency latency and cost in summary ipv6 unicast is one-to-one type of communications multicast is one-to-many type of communications anycast is one to any one of the group over type of communications when we've seen that anycast packet we mean send the packet to the closest member of this group I hope this video is helpful thank you very much and see you next time oh don't forget to subscribe you [Music]
