wrote: 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.
fc00::0/7 already *is* *the* prefix, so routers need not provide it. Do not confuse it with prefix in RA (router advertisement).
No, the router needs to provide the 64 bits prefix which begins with fc or fd (fc00::/7) on the link, which should be unique in the company network, provided this is a link without further routers.
fc00::0/7 is so called Unique Local Unicast Address. See https://tools.ietf.org/html/rfc4193 for details. Initially fc00/7 was reserved for addresses provided by global registration authority; currently these addresses are reserved and undefined.
So the question still remains - where this address comes from and who tries to configure it and why this configuration attempt is apparently unsuccessful and is retried permanently.
This has been answered already, the Wi-Fi router provides them, so this should be disabled. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
