> [What is setupVars.conf and how do I use it?](https://discourse.pi-hole.net/t/what-is-setupvars-conf-and-how-do-i-use-it/3533)

so do i edit this .conf file? e.g. using nano?

Then "pihole -r"?

If so, how do i configure additional IP4 addresses?

For example, can i set "PIHOLE\_DNS\_3" to an IP4 address?

Can i add additional PIHOLE\_DNS lines? e.g. "PIHOLE\_DNS\_5="

Thanks.

`sudo nano /etc/pihole/setupVars.conf` will get you into the editor. Make the changes, save and exit.

Then `sudo service pihole-FTL restart` will restart FTL.

Yes. Change existing lines as needed, or add new lines, or both.
