A combination of the local-link prefix FE80 and the 64-bit IPv6 identifier

They are randomly generated and then prefixed with FFCC

Detailed explanation-1: -The link-local address of a node is the combination of the prefix fe80::/64 and the 64-bit interface identifier expressed in IPv6 colon-hexadecimal notation. Therefore, the link-local address of this example node with the prefix fe80::/64 and the interface identifier 02-60-08-ff-fe-52-f9-d8 is fe80::260:8ff:fe52:f9d8.
Detailed explanation-2: -Typically, link-local IPv6 addresses have “FE80” as the hexadecimal representation of the first 10 bits of the 128-bit IPv6 address, then the least-significant 64-bits of the address are the Interface Identifier (IID).
Detailed explanation-3: -Link local addresses are used inside an internal network, are self-assigned and start with “fe80:” as the prefix group. Unique local addresses. This is the other type of internal address that is not routed on the internet.
Detailed explanation-4: -Link-Local Unicast Address Hexadecimal representation of the 10-bit binary prefix 1111111010. This prefix identifies the type of IPv6 address as link local.
