Detailed explanation-1: -the FE80::/10 are the link local addresses. It is correct that you don’t see them in the routing table: as explained in a previous thread actually it is a single IPv6 /64 subnet using eui-64 format what you get.
Detailed explanation-2: -A 64-bit interface ID is created by inserting the hex value of FFFE in the middle of the MAC address of the network card. Also, the 7th Bit in the first byte is flipped to a binary 1 (if the 7th bit is set to 0 it means that the MAC address is a burned-in MAC address).
Detailed explanation-3: -EUI-64 (Extended Unique Identifier) is a method we can use to automatically configure IPv6 host addresses. An IPv6 device will use the MAC address of its interface to generate a unique 64-bit interface ID. However, a MAC address is 48 bit and the interface ID is 64 bit.
