I am sorry if there's already a thread about this. I tried my best looking for the same ubuntu version but I only saw this: After modifying /etc/hosts which service needs to be restarted?

We're using ubuntu 16.04.06.

Do I have to restart my services after some edit/config?

I'm sorry again if I only need a confirmation about my problem. Thank you for the help

No, you don't need to restart anything after making changes. If the DNS is still cached somewhere then you may want to clear it. As far as I know, with normal operation, that's it.

To clear systemd-resolve's cache:

sudo systemd-resolve --flush-caches

If you want to verify that you cleared it out:

sudo systemd-resolve --statistics

It should read:

Current Cache Size: 0
