Static IP setup can be pretty simple: # dpkg -S systemd | grep workd | grep lib systemd: /usr/lib/systemd/system/systemd-networkd.socket systemd: /usr/lib/systemd/system/systemd-networkd.service systemd: /usr/lib/systemd/systemd-networkd systemd: /usr/lib/systemd/systemd-networkd-wait-online systemd: /usr/lib/systemd/system/systemd-networkd-wait-online.service systemd: /usr/lib/systemd/system/[email protected] systemd: /usr/lib/systemd/system/systemd-networkd-persistent-storage.service # cat /etc/systemd/network/eth0.network [Match] PermanentMACAddress=<MAC address> [Network] Address=<IP/IP> DNS=<IP> [<IP>]...
