systemd-networkd

With a systemd-ful environment, you can run the network daemon (i.e., systemd-networkd). Once enabled, you can run networkctl to list all of the network devices. 1

networkctl

  2 enp1s0 ether    routable    configured
  3 wlan0  wlan     routable    configured

To configure network manager, you can create a network file in one of systemd unit file paths in the system. Each of the device will be assigned an IP address. You can either assign an IP address or dynamically assign them in some way. One of the common ways to do dynamic IP addresses is installing a DHCP server (which is another thing to be configured). Here's an example of configuring any wireless devices and assigning a dynamic IP addresses with DHCP.

[Match]
Type=wlan

[Network]
DHCP=yes
IPv6PrivacyExtensions=yes

[DHCPv4]
RouteMetric=1024

[DHCPv6]
RouteMetric=1024

You can also run ip address for it.
