To the best of my knowledge, Windows actually generates three addresses…
1. Subnet Stable quasi-randomized address unrelated (or at least not reversable to) MAC address. 2. Privacy address which rotates frequently (for some definition of frequently). 3. Stable address related to MAC address.
The 3rd one is standard SLAAC. The second one is standard privacy extensions. THe first one is unique to Windows. You’ll get the same address every time you connect to the same subnet, but you won’t see that suffix for that host on any other subnet.
It’s not exactly specific to Windows, dhcpcd use a something like that (my IPv6 is 2a00:5884:8316:2653:fd40:d47d:556f:c426). And at least, there is a RFC related to that, https://tools.ietf.org/html/rfc7217.
Yes, but in the case of Windows, that happens with SLAAC without DHCP. TTBOMK, this is unique to windows. Owen
