An IPv6 multicast address for well-known link-local messages would start with “FF02” and you may recognize that FF02::1 is the all-nodes link-local multicast group address. Only IPv4 has broadcast as a method of sending one packet to ALL nodes on the current LAN.

The link-local addresses are defined by RFC4291 and have a fix format, hence we do not need to configure the prefix length. 2.5.6. Link-Local IPv6 Unicast Addresses. Link-Local addresses are for use on a single link. IPv6 Global Address, Unicast Local Address and Link Local

Link-local IPv6 addresses are used as part of the IPv6 network auto-configuration process. Instead of getting an address via DHCP, a NIC will hop on the network with a link-local IPv6 address and with this will have to ability to do further configuration automatically (soliciting neighbors, router, et cetera).
Windows operating systems don’t use EUI-64. The IPv6 address is calculated by using a random value. The MAC address has no influence on this. The lack of FFFE indicates that EUI-64 is not used. Here’s an example of a random generated IPv6 Link-Local Address. Get-NetIPConfiguration | Select-Object IPv6LinkLocalAddress
If the derived link-local address is a duplicate, stateless address autoconfiguration for the IPv6 protocol for Windows Server 2008 and Windows Vista can continue with the receipt of a multicast Router Advertisement message containing site-local, unique local, or global prefixes. How to access devices with IPV6 link local address from A link local address can be valid on multiple links. If for example your system has both Ethernet and Wi-Fi those might be connected to different networks. Therefore you need to add a scope identifier to a link-local address. The syntax for that is to add % and the scope to the IPv6 address.
