+### `iproute2`
+
+The `iproute2` package provides a collection of networking and traffic control utilities. Once again, Debian doesn't ship all of these, only those deemed **necessary**.

+
+The Debian installer automatically configures Ethernet and/or Wi-Fi if an interface is available. To change such configurations, edit `/etc/network/interfaces`.
+
+Both DNS and DHCP are managed by `systemd-resolved` and `dhclient`, respectively.
+
+### Network Manager
+
+To facilitate configuring networks, it's very common to install Network Manager on top of Debian's default utilities.
+
+```bash
+sudo apt install network-manager
+
+# Remove the current configuration (so NM can take over)
+sudo mv /etc/network/interfaces /etc/network/interfaces.bckp
+sudo systemctl restart networking
+sudo service NetworkManager restart
+```
+
+After Network Manager is enabled, the `nmtui` command can be used to easily connect to new networks and change configurations.
