so is it using dnsmasq but he custom FTLDNS version
wouldn't that be better worded as FTLDNS instead of dnsmasq to avoid confusing with normal dnsmasq as the options are slightly different from normal dnsmasq now
04-pihole-static-dhcp.conf was exactly the same as what you would find in dnsmasq
the syntax has changed slightly in V6 as its now in pihole.toml
or am I completely wrong here
