Converting a MAC address to an EUI-64 address

FIGURE 2 . 8 Converting a MAC address to an EUI-64 address
The site-local unicast addresses use the prefix range FEC0::/10, which is padded with 38 0s
and then appends the 16-bit subnet identifier, followed by the 64-bit interface ID. Figure 2.9
shows the format of the site-local unicast address.

Link-Local Unicast Address
A link-local unicast address is used in the neighbor discovery protocol and is used only on the
local link network. This is used by the stateless auto-configuration process for devices to discover
the Data Link layer address of the network and to find and keep track of neighbors. A
link-local unicast address uses the prefix range FE80::/10, which is padded with 54 0s, followed
by the 64-bit interface ID. Figure 2.10 shows the format of the link-local unicast address.
