Detailed Explanation
systemd-networkd is a system daemon that manages network, can detect and configure network devices and is also capable of creating virtual network devices configurations sinde 2010. systemd-network can be especially useful to set up complex network configurations for a container managed by systemd-nspawn or for virtual machines. This site explains technical details including system service dependencies of systemd-netword.
The default network management moved to netplan[1] from the Ubuntu 20.04 server, so admin is able to configure various network configuration by modifing /etc/netplan/*.yaml file and netplan commands.
To use systemd-networkd, start/enable systemd-networkd.service.
There are two different network managers can be installed on the same system at the time this post is wrote. by default, HPCMATE's automated server setup script disabled NetworkManager to avoid potential confliction between systemd-networkd service.
Networkctl is a command line utility which has been developed in order to show a summary of the network devices in the system and their respective connection status, in addition, with networkctl it will be possible to consult and control the Linux network subsystem.[2][3] <syntaxhighlight lang="bash"> $ networkctl --help

Best Practices
- 최신 버전 사용 권장
- 공식 문서 참고
- 테스트 환경에서 먼저 검증
