Depends on how you install. > There is an alternative to NM on Debian 12? ALL installations of ALL versions of Debian support "ifupdown", also known as /etc/network/interfaces, for configuring the network. If your system is NOT a laptop, and doesn't move around from place to place, this is probably what you want. Servers? Ethernet-based workstations? This is probably what you want. If you install a Desktop Environment when you install Debian, then you probably also get Network Manager. This is designed for laptops and other systems whose networking may change at any time, or for systems that rely on wireless networking rather than ethernet. If that describes your system, then this is probably what you'll be using. Debian also supports systemd-networkd for configuring the network. This is available, but is not configured by default. If you want to use this, you may do so. I know very little about it, so I can't tell you what use cases it's best for. Ultimately, Debian offers flexibility and choice. Use whatever works best for you and your systems.
