A link-local address is for use on a single link and should never be routed.
IPv6 Link Local addresses are identified among IPv6 addresses by reserving the left most 64 bits as translates to FE80 in hexadecimals. IPv6 Link Local addresses are used by devices for communicating with other nodes on the same link. The scope of an IPv6 Link Local address is the local link.
Read below. We already know the first 64 binary bits of IPv6 Link Local addresses are reserved as FE But, MAC addresses are 48 bit numbers. The answer is, an hexadecimal number "FF: Also the 7th bit from left in the MAC address is flipped.
Please explain if you will. In IPv6 ,  link-local addresses are mandatory and required for the internal functioning of various protocol components. So what are all those FE A careless recursive chmod was the culprit. In IPv6, addresses may be assigned by stateless automatic or stateful manual mechanisms. Feel free to email them at temp akrin.

Which means, if the 7th bit in the MAC address from left is 1, change it to 0 or if the 7th bit from left in the MAC address is 0, change it to 1. So i could understand… how it is???
I am just confused on when this will be or won't be used? When an IPv6 host first becomes active on a link, it can self-configure its own interface address. The first step in this process is the determination of the bit Interface ID portion of the address. So it makes perfect sense.
What about VMs, virtual hosts? To me it looks like they have no other choice but to use a self-assigned MAC i. So - if the bit is already flipped there's no need to flip it again. Find A Community.
