Get dhcp IP address at boot
 
I just installed Arch for the first time. I would like by network interface, enp0s25, to get a dynamic ip address at boot. How do I do this?

I read this document: https://wiki.archlinux.org/index.php..._using_systemd, and under: "Persistent configuration on boot using systemd" the document tells how to get a static ip address at boot. I want a dynamic IP address though. Any help would be much appreciated. Thanks.

I forgot to mention that this is what I run to assign the IP address:

Code:
dhcpcd enp0s25
Not sure if best practice is to just add that to some startup script or not, and if so, which one? Thanks.

Code:
# systemctl start dhcpcd.service
# systemctl enable dhcpcd.service

Make sure all other network-related services are stopped & disabled or they will conflict with dhcpcd.

That worked.

So 'interface_name' actually means the name of the service, which is dhcpcd right?
No.

If you want to use the interface-specific service (for example, if you are assigning static ip's to your wireless interface) you can use:
Code:
# systemctl start dhcpcd@enp0s25.service
# systemctl enable dhcpcd@enp0s25.service
