 ### IPv6
 
+#### IPv6 Privacy by Default
+
+Create `/etc/NetworkManager/conf.d/01-ip6.conf`:
+
+```conf
+[ipv6]
+ip6-privacy=2
+```
+
+#### EUI64
+
 Set address generation type to eui64 with nmcli:
 
 ```bash
 nmcli connection modify Wired\ connection\ 1 ipv6.ip6-privacy 0
 nmcli connection modify Wired\ connection\ 1 ipv6.addr-gen-mode eui64
 systemctl restart NetworkManager
+```
+
+You can also start an interactive session to edit a connection:
+
+```bash
+nmcli connection edit Wired\ connection\ 1
+
+# Show all current settings
+print
+
+# Set something
+set ipv6.ip6-privacy 0
+set ipv6.addr-gen-mode eui64
+
+# Save the changed setting
+save
+
+quit
+```

+[device-mac-randomization]
+# "yes" is already the default for scanning
+wifi.scan-rand-mac-address=yes
+ 
+[connection-mac-randomization]
+# Randomize MAC for every ethernet connection
+ethernet.cloned-mac-address=random
