Where do you see them, in ifconfig, ip addr?

Either ifconfig or ip -6 address show

Let me see, I have:

inet6 addr: fe80::221:85ff:fe16:2d0b/64 Scope:Link
inet6 addr: fc00::14/64 Scope:Global

The second one I recognize as having created it myself, manually. And
the first one is constructed from the MAC. Maybe the address you mean is
only generated when the router hands over a prefix? (which it doesn't,
as I don't have IPv6)

You don't have any global unicast addresses. Those generally start with
2. The unicast addresses, either random or MAC based are created with
"SLAAC", which relies on router advertisements.
