systemd-networkd not getting DHCP address

I have a very basic brand new Arch install onto an Intel NUC version NUC7i3BNH.  It has an Intel i219-V ethernet adapter that is named "eno1" according to "ip link show". After install, I created a basic networkd file located at /etc/systemd/network/eno1.network" according to the wiki instructions. It is shown below:

[Match]
Name=eno1

[Network]
DHCP=ipv4

I have enabled the systemd-networkd service by running "systemctl enable systemd-networkd". But it is not working: upon boot, the adapter does not get an address. I have tried changing "DHCP=ipv4" to "DHCP=yes" but this changed nothing.

The only journal output related to systemd-networkd is shown below:

Jan 26 11:09:08 NUC systemd-networkd[271]: eno1: Gained carrier
Jan 26 11:09:09 NUC systemd-networkd[271]: eno1: Gained IPv6LL

Restarting systemd-networkd does nothing. If I manually run "dhcpcd eno1", I immediately get an address with no problem. It is almost like systemd-networkd is completely broken.

What is going on here? Seems pretty basic of a thing not to work.....

Re: systemd-networkd not getting DHCP address

0) what does networkctl show?

1) enable networkd debug!

systemctl edit systemd-networkd.service

and enter:

[Service]
Environment=SYSTEMD_LOG_LEVEL=debug

2) tcpdump -i eno1 -nv port 67 or port 68
