What does 'host [device]' show? Is an IPv6 address returned? So long as you have DNS resolution, the actual IP address doeasn't matter, at least that is the "official" impression I've gotten. However, I wasn't satisfied with pseudo random interface addresses and went searching for a solution, particularly with Network Manager and systemd-networkd and I found solutions for each in the form of tokens. For Network Manager the command is something like: nmcli connection modify Wired\ connection\ 1 ipv6.token ::3 Where "Wired\ connection\ 1" is the connection name. This results in 'host' returning: # host device device.home has address 192.168.1.3 device.home has IPv6 address fd01:xxxx:xxxx:xxxx::11f device.home has IPv6 address 2000:xxxx:xxxx:xxxx::11f device.home has IPv6 address fd01:xxxx:xxxx:xxxx::3 Then I set a static DNS record for the ::3 address. The "::11f" address is conjured up by Network Manager and while pseudo randomi, it is stable. I had tried forcing the issue with DHCPv6 to no avail. Similarly, I configured systemd-networkd by adding: [Network] DHCP=yes IPv6PrivacyExtensions=true [IPv6AcceptRA] Token=eui64 Token=::1 This results in IPv6 addresses I can recognize. By adding the options for privacy extensions and eui64, random temporary IPv6 addresses are generated. These are mostly used by browsers and will be seen as the address in use from IPv6 test sites. It is not unusual to see six to ten IPv6 addresses assigned to an interface. HTH, - Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
