Which IP address and why do you think so?

As we are not with you all the time, we have no idea what you are doing and seeing. Always show!

And please not only output, but include the line with the command at the begin of a copy/paste. Then we can see what you did and got.

Same for what looks like a part of a DNS server configuration, but we have no idea where it is from. The same system, another one, when another one, where and how is it configured in the one where you think resolution fails?

Firts thank’s for reply !!
why . because the ping to for exemple glpi retur an error "name or service not know

As i did’nt say this DNS is only for my intranet. I have a DNS on the box and i use DNS from google in the DHCP parameters
I can’t put a screenshot on the site to show you other parameters. xhich one do you want to know ?

the output of the status of named

Then you should SHOW that ping! so that everybody can take conclusions for her/himself and try to help you not on the base of your conclusions.

On the same “box” as the one you try the ping from?

Again, where is the configuration that should make your resolver use that DNS server.

cat /etc/resolv.conf

And maybe

host glpi

Hi
I talk about ping , but all other action are wrong ( url adresse, nslookup . )
the commande are from any PC in the lan

The box in 192.168.0.1 with dhcp
Please find resolv.conf

@Enthalpie

On How To Post CODE.

You did the correct formatting in post #4. And now you do it wrong. ???

But in post #4 (and all other similar posts) the command is missing.

Example:
Thus NOT

This is the output from uname

Linux boven 6.4.0-150600.23.47-default #1 SMP PREEMPT_DYNAMIC Thu Apr  3 03:44:04 UTC 2025 (2854fd7) x86_64 x86_64 x86_64 GNU/Linux

But simply

henk@boven:~> uname -a
Linux boven 6.4.0-150600.23.47-default #1 SMP PREEMPT_DYNAMIC Thu Apr  3 03:44:04 UTC 2025 (2854fd7) x86_64 x86_64 x86_64 GNU/Linux

Only one copy/paste and no story telling.

Further about your problem

But ping is a good representative of the problem and thus easy to show. And you also did not post nslookup or any other one.

And nslookup at least shows which server it tries.

I can tell you one thing for sure. When people ask you to provide proof of what you say and also more information by asking to post command with output, then you better do it (or provide a very good reason for not doing it), else they will leave the thread for some more rewarding activity.

OK but it is difficult to copy from xterm,
it is ok from me to cut from file. I certainly not know how to copy from xterm, i use terminal and it is ok!!

I do not see anywhere what is listening on this address. Show

ss -lunp 'sport == 53'
16

Everybody here does that all the time!

17

Am I correct that web-free is the domain name used in the LAN?

Then, what does

nslookup glpi.web-free

do?

18

Not at all: use mouse to select, hit Ctrl-Shift-C.
Or pipe the command through to susepaste: <command> | susepaste. Post the returned URL here.
