Just to check, I went back and purged ifupdown, then enabled networkd on a test host. I used this simple configuration: ***** [Match] Name=en* [Network] DHCP=yes IPv6PrivacyExtensions=yes IPv6LinkLocalAddressGenerationMode=stable-privacy ***** NOTE: my sysctl.conf includes the following: # Generate IPv6 Stable Privacy addesses instead of EUI64 net.ipv6.conf.all.addr_gen_mode=3 net.ipv6.conf.default.addr_gen_mode=3 # Enable IPv6 Privacy. Prefer random over EUI64 derived. net.ipv6.conf.all.use_tempaddr=2 net.ipv6.conf.default.use_tempaddr=2 What networkd gives me: 1) networkd insists on generating a second stable-privacy local-link, in addition to the one produced by the kernel, because the IPv6LinkLocalAddressGenerationMode key is set. 2) Despite this, the mngtmpaddr address still uses eui64. I'm probably missing something that would be obvious to systemd gurus. What exactly? Martin-Éric
