But the same ping test to Quad9 was working well before
```nohighlight
ping -c 1 -W 10 dns9.quad9.net
```
Seems something with your VM or did you changed anything in between?

Are you using same DNS server on windows as well as on the VM?
But as said, this was working fine before on another test you did

DNS is 1.1.1.1 and 8.8.8.8 on the router.
and the behavior now is the same behavior as past, always.
DHCP was fine, once switched to static, it stopped working immediately.
Could you test yourself using the VM image on the site?

OK. found that in Dietpi-Config Quad9 DNS entries are 9.9.9.9 and 149.112.112.112
But on Windows using ping
ping [dns9.quad9.net](http://dns9.quad9.net) got
Pinging [dns9.quad9.net](http://dns9.quad9.net) [149.112.112.9] with 32 bytes of data:

does it make a difference?

112 at the end is correct as you can see on this overview. [https://en.m.wikipedia.org/wiki/Public\_recursive\_name\_server](https://en.m.wikipedia.org/wiki/Public_recursive_name_server)

pinging ip address is OK in DietPi, but ping a name got Temporary failure in name resolution error.
What’s the command to find out what DNS server I’m using on Linux?
And what’s the equivalent of Windows NSLookup?

Should be configured in this file

Answering my own question: need to execute the following command to install
apt install dnsutils
==
I switched back to DHCP and ping [www.firefox.com](http://www.firefox.com) and it immediately worked.
```plaintext
ping www.firefox.com
PING dzlgdtxcws9pb.cloudfront.net (13.33.185.129) 56(84) bytes of data.
64 bytes from server-13-33-185-129.sea19.r.cloudfront.net (13.33.185.129): icmp_seq=1 ttl=242 time=153 ms
```
If static IP then will get Temporary failure in name resolution error.
```plaintext
root@DietPi:~# ping www.firefox.com
ping: www.firefox.com: Temporary failure in name resolution
```

So the verdict is:
Whenever dietpi-software launches, it will run
ping -c 1 -W 10 [dns9.quad9.net](http://dns9.quad9.net)
no matter what DNS entries I set at ethernet network configuration
It always fails if I set static IP for the VM, and
it always succeeds if I use DHCP for the VM.
And dietpi-software is not able to continue further if the command
ping -c 1 -W 10 [dns9.quad9.net](http://dns9.quad9.net) fails.
well, actually every ping command that pings a full qualified domain name fails once static IP is set.

I downloaded and installed the Native PC for BIOS/CSM image on a physical machine, exactly the same issue.
Once set a static IP, DNS resolver doesn’t work and Dietpi-Software refuses to proceed.

Sounds like a port security issue.
Have you tried to change to static IP other devices in the network or only this PC?
Can you tell us more about the topology that you have?

Very simple topology.
Only 2 PCs and Android smartphones devices behind DSL modem + router in 192.168.0.x range. Main PC running VMWare pro 16. x86 VM using bridged network card that ether bridged to main PC’s Intel gigabit network card with IPv4/IPv6/etc protocols that Windows 10 installed or to a Realtek Gigabit USB 3.0 adapter which removed all protocols except VMware Bridged Protocol, same result.
Also the same result for the other physical PC.

Therefore it has something to do with the modem/router, not dietpi.
