What Type Of Ipv6 Address Is Fe80::8cf1:2c42:Ffde:Da1c?

What Type Of Ipv6 Address Is Fe80::8cf1:2c42:Ffde:Da1c?

 Fe80::8cf1:2c42:Ffde:Da1c is the type of the link-local address. Today let us know about what actually link-local address. The link-local address is one of the unicast addresses.

The range of the link-local addresses is FEBF:1111 1110 1011 1111.

Let us actually know what is a link-local address. The term link represents the network segment that is separated by the router and the term link-local represents that it is local to the link in which it is present.

This link’s local address will be used in order to communicate with one device to another device on the link in which it is present. This must consist of only a single link that is unique.

There is another point that to be noted is that this link-local address will not be present in the routing table of the IPv6 address. Each IPv6 device must consist of at least one link-local address in it.

Here, nothing will happen if there is no Global address but the link-local address must be given to the system.

Now let us know the advantages of the link-local address in detail. The main advantage of this link-local address is that if one device wants to boot up, then it will automatically give the link-local address to it.

By using the link-local address it can also communicate with the other device that is present in the network.

Normally this link-local address will automatically be created by the device that is present in a network. It is one of the main advantages of the link-local address.

Now let us know the structure of the link-local address. The first 10 bits will be the same in all link-local addresses which is

FE80. And the next 64 bits will be the interface ID. This interface ID can be done automatically by using EUI-64. This will use the Mac address.

Now let us take an example in order to understand this concept in detail. We will use an Ethernet Mac address in order to create the 64 bit interface ID. There is also another way is that we can statically configure the interface ID.

This link’s local address can be automatically generated in the computer when the computer gets booted up. The link-local address name itself suggests that it is only valid in the local area network, which means the communications will be taken place only on the local area network.

Hear the routers will not forward the packets with the link-local address.

It is a must to have the link-local address in every IPv6 device. Because there will be no communication between the devices if no link-local address is present.

Now, this link-local address is mainly used by the protocol called as in NDP. The term NDP stands for neighbor Discovery protocol. This neighbor Discovery protocol is used in order to discover the library notes that are present on the same link.

We can also say that this neighbor Discovery protocol will be similar to the address resolution protocol.
