dhcpd after reboot

[cincuranet]

I'm trying to setup DHCP server on Raspberry Pi, but I'm having small problems starting it properly after boot.

My dhcpd.conf is:
$this->bbcode_second_pass_code('', '
authoritative;
ddns-update-style standard;
ignore client-updates;

subnet 192.168.66.0 netmask 255.255.255.0 {
range 192.168.66.100 192.168.66.199;
option subnet-mask 255.255.255.0;
option routers 192.168.66.2;
option domain-name "foo.local";
option domain-name-servers 8.8.8.8, 8.8.4.4;
default-lease-time 1200;
max-lease-time 1200;
}
')

The dhcpd4.service:
$this->bbcode_second_pass_code('', '
[Unit]
Description=IPv4 DHCP server
After=network.target

[Service]
Type=forking
PIDFile=/run/dhcpd4.pid
ExecStart=/usr/sbin/dhcpd -4 -q -pf /run/dhcpd4.pid
KillSignal=SIGINT

[Install]
WantedBy=multi-user.target
')

But after the Raspberry Pi is rebooted I get:
$this->bbcode_second_pass_code('', '
* dhcpd4.service - IPv4 DHCP server

Jan 01 01:00:13 x2raspi dhcpd[117]:

')

Forcing eth0 (the network card):
$this->bbcode_second_pass_code('', '

Loaded: loaded (/usr/lib/systemd/system/dhcpd4.service; enabled)
Active: failed (Result: exit-code) since Thu 1970-01-01 01:00:13 CET; 44 years 6 months ago

Jan 01 01:00:13 x2raspi dhcpd[117]:

Jan 01 01:00:13 x2raspi dhcpd[117]:
')

I believe it's because it starts before the IP address from /etc/netctl/eth0 was fully assigned. The eth0 file is:
$this->bbcode_second_pass_code('', '
Description='A basic static ethernet connection'
Interface=eth0
Connection=ethernet
IP=static
Address='192.168.66.4/24'
Gateway='192.168.66.2'
DNS=('8.8.8.8' '8.8.4.4')
ExecUpPost='/usr/bin/ntpd -gq || true'

## for DHCPv6
#IP6=dhcp
## for IPv6 autoconfiguration
IP6=stateless
')

Is it really because the IP address has not yet been configured? And if so, how I can make it start after it's configured (I tried also network-online.target, but that didn't help)?

I'm not going to be much help because I'm going to suggest using dnsmasq.
A heads up also, systemd-networkd will be the default on images, took me minutes to figure out dhcp Ethernet and ntpd replacement (systemd-timesyncd)
