Yes, and SLAAC is what rfc7217 is about > TTBOMK, this is unique to windows. Nope. See for example the stable_secret setting in https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt But Linux doesn't create this in addition to the EUI-64 derived address. It creates in instead. And it won't happen by default. Only if you configure a secret. Except for weird interfaces without any EUI-64 identifier, like raw IP interfaces, which will use this code to support SLAAC. How does Windows manage to *use* three addresses? I can understand how the rfc7217 address and the privacy address can be use for different purposes, but what do they use the EUI-64 address for? Bjørn
