I know there probably isn't a "right" way to do this but, while I've
been trying to sort out how to make my dns/dhcp more resilient, I have
looked at my existing dnsmasq running on a Pi and it looks a bit odd
to me.
It's a pretty standard, off the shelf Raspberry Pi installation using
the Lite version as it's headless. The dnsmasq.conf file has been
changed quite a lot over the years though and I wonder if it's still
optimal.
The upstream servers *seem* to be specified in /etc/dhcpcd.conf as
follows:-
# Example static IP configuration:
interface eth0
static ip_address=192.168.1.2/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
static routers=192.168.1.1
static domain_name_servers=192.168.1.2 1.1.1.1 212.159.13.49

this is dhcp client configuration, not dhcp server.
iiuc it tells dhcp client not to use IP address, default route nor servers
that DHCP server provided.

This *is* the DHCP server for my LAN so these are the upstream DNS

- why do you run a DHCP client on a DHCP server then?
- Especially when you configured it statically and not to use DHCP settings?
note that this is dnsmasq list, not dhcpcd.

Because that's what you get if you install dnsmasq and very little
else on an 'out of the box' Raspberry Pi.

And there's nothing wrong with it. Many home routers incl. OpenWrt run
dhcpd to get upstream information, and use dnsmasq to distribute
everything to every device behind the router.
those routers usually get their IP address, default route and DNS servers from
DHCP upstream servers.
In this case, all those parameters were hardly overwritten (apparently by
instalator), which is strange, but the OS _MAY_ contain scripts that use
information from DHCP client to configure dnsmasq (e.g. dns server list)
I can only guess now.
since the dnsmasq.conf has been changed, it's hard to say if it's optimal.
I use dnsmasq on my router, which takes dns servers dynamically, which I
believe is safer than using static list.
