tcpdump, resolv.conf and leases output
I have the router on my lan configured to provide "Domain-Name-Server Option 6"
with a list of dns servers to every client requesting a dhcp lease.
The dns servers are listed in order of preference. I am trying to achieve that
local dns server is the primary resolver for clients.
In the attached txt file you can see some output of tcpdump, /etc/resolv.conf
and /run/systemd/netif/leases/*.
In my example 192.168.178.70 is my local dns server and 212.54.44.54 is my
upstream dns server.
No matter in what order my dhcp server serves the name server list in dhcp
option 6 (see tcpdump output), systemd-networkd always puts the 212.54.44.54 on
top in /etc/resolv.conf.
I could not find any documentation describing this as expected behaviour.</pre>
