DHCP configuration file

[javiermi]

Forgive me if this has been answered before
I'm trying to add manually  50+ static addresses, and I have seen a few forum entries saying how they have done it
However, I just cannot figure out WHAT file I need to edit
If I do a search for dhcpd.conf I get a few files, but those ones don't seem to have the current configuration:
root@OPNsense:/home/javier # find / -name dhcpd.conf
/usr/local/etc/dhcpd.conf
/usr/local/opnsense/service/templates/OPNsense/Syslog/local/dhcpd.conf
/var/dhcpd/etc/dhcpd.conf

Or is another file?
Thanks
