Why one interface has two addresses [SOLVED]

Support Network
6

Actually, if I disable both NetworkManager and dhcpcd I still get the 192.168.0.18 address at boot, the log shows:

Oct 30 09:13:49 gandalf dhcpcd[934]: enp6s0: leased 192.168.2.18 for 259200 seconds

What’s calling /usr/bin/dhcpcd I wonder ?
