This would appear to show that your interface wlan0 is switching between two addresses, the fe80 and the fc00 prefix.
I would like to know where the fc00 address is coming from.
fe80 addresses are only usable in the broadcast domain of the network (link local address). fc00::/7 is a prefix used in a network of local importance, like a company network (for an international company this can be worldwide). It is a bit comparable with the 10 network for IPv4. Its purpose is to have simple filters on the edge of the network. Routers in the local network provide the prefix used for this type of address on the link. So apparently your system is connected to a router which is part of such a company network. In that case your system should have at least 3 IPv6 addresses, a fe80, a fc00 and a global address if your router is also connected to a world global IPv6 network. You may even have more than one world global network addresses, the last 64 bits derived from your MAC address, randomly generated and a fixed one received from a DHCP6 server or defined on your system.
That makes two questions then - a) why does Carlos have an FC00 address on his network? b) why does it change/toggle all the time? Carlos, sounds like it might be coming from your router. -- Per Jessen, Zürich (14.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
