Connection suprisely works without dhcpcd

When I  installed my system I forgot to set-up connection, and I couid not connect to any site, or just ping 8.8.8.8. But today I found, that I easily connect to any site without dhcpcd.

PC1-noqrax[~]: ps -e | grep dhcpcd
  667 ?        00:00:00 dhcpcd
PC1-noqrax[~]: ping -c3 8.8.8.8

PC1-noqrax[~]: sudo systemctl stop dhcpcd.service

Please clarify it to me!

Read the wiki: https://wiki.archlinux.org/index.php/Ne … IP_address

$ ps -e | grep dhcpcd
$ ps -e | grep systemd-network
  231 ?        00:00:00 systemd-network

By default (at least I'm pretty sure I never changed anything) /etc/dhcpcd.conf has "persistent" set, so the interfaces stay configured after dhcpcd exits (but the leases won't be renewed).

Thank you, you are right!
