When nslookup google.com from a laptop on this LAN, it returns Server: 10.2.0.1 Address: 10.2.0.1#53
nonauthoritative answer: google.com with ip information repeated.
I don’t under stand this return as it’s an ip outside my lan net and dhcp provisioning.
I’m unclear on what you’re confused about regarding the above quote. Here comes an explanation of nslookup.
The command is nslookup <domain> <dns-server> and if dns-server is empty it uses your default. F.e.:
***@fedoragaming:~$ nslookup www.google.com 8.8.8.8
The response starts by telling you which <dns-server> it used for the lookup and which address including port was used:
Server: 8.8.8.8
Address: 8.8.8.8#53
It then gives you the answer on where to find the <domain>, once for ipv4 and once for ipv6:
Non-authoritative answer:
Name: www.google.com
Address: 142.251.142.228
Name: www.google.com
Address: 2a00:1450:400f:807::2004
edit: I think I understand your question a bit better now. To check which dns-server you’re using do a “cat /etc/resolve.conf”
If you run a distro with systemd then use the command “resolvectl status”
