=> I can answer, from man ifconfig:
eui64 (inet6 only) The real IPv6 address is computed by replacing the
last 64 bytes of the given address with the Interface Identifier.
For a point-to-point interface, if a destination address is given
and has a null Interface Identifier part, the Interface Identifi-
er part of this destination address is filled by the Interface
Identifier part of the link-local destination address (which must
The interface ID is picked up from the (first) link-local address and
if there is none from the link-layer address. There is a provision for
point-to-point links (i.e. set the peer interface ID too). The last versions
perform this in ifconfig itself but you can implement the same idea in
the kernel or in a script.
