You can now manage on your IPv6 addresses. But, you will wonder, why is that their is more than one IP address found with just only one device? The answer is simple. It is put there for you to read this article.
Link Local Address always starts with FE80 : : … : … . : .. : As you enable your router, this address is generated directly as one of your addresses. Now, how does the router know about your address? How was it generated?
Remember with your MAC Address? This is the one used to generate a Link Local Address. Check this:
Host A for example has a 0000.1111.1111 for its MAC Address.
First thing to do is cut that address in half. So, it becomes 0000.11 \ 11.1111..
Next, insert characters in the middle… Constantly, those characters are FFFE
The output would be: 0000.11FF.FE11.1111
then, if we are going to elaborate the binary equivalence for the above item is:
0000 0000 0000 0000 . 0001 0001 1111 1111 . 1111 1110 0001 0001. 0001 0001 0001 0001
you will count from the very left from 1 to 7… Then flip the seventh one.. example..:
0000 0010 0000 0000 . 0001 0001 1111 1111 . 1111 1110 0001 0001. 0001 0001 0001 0001
then,.. convert again back to hexadecimal like this:
0200.11FF.FE11.1111 . Omit unused zero. The output then become this with the correct separator for IPv6.
The result is what we called Link Local Address.
