as the host portion of the address. When your computer is on for a while, you'll see a list of previously used addresses, which are still valid, but eventually those addresses will fall off the end of the list. Only the newest one is used for outgoing connections. 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. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
