Diagnostic and resolve dns lookup

[frankz]

Hello everyone, in the pfsense diagnostics if I type a host that does not exist at the domain level it returns valid ips to me.

69.172.169.161 => 69-172-169-161.cable.teksavvy.com.

pfSense version ?
I presume you've changed the default DNS settings. Yes ? Why ?
Possible that you get back to the default settings "the ones that work (better)" ?

I managed to get the same result :

but why ?

tell me how you did it, and I tell you how I did it

@Gertjan Sorry but the translation eng ita does not make me understand. The settings are the standard 127.0.0.1 and forwarding to external dns . I have been using the DNS Resolver for years . But if I try from a client no error . Pf 2.7.2

That's the answer : you forward to some external DNS, and when you asked it : what is the IPv4 of "noexisthost.local.lan" it answered : 69.172.169.161

The other answer was what I did :
I created a host override for "noexisthost.local.lan" so it points to 69.172.169.161
This is indeed problematic.

Can you tell to who you forward ?

You mean : you get the NXDOMAIN error message ?

C:\Users\Gauche>nslookup noexisthost.local.lan
Serveur :   pfSense.bhf.tld
Address:  2a01:cb19:907:dead:beef:77ff:fe29:392c

*** pfSense.bhf.td "not succeeded to find"** noexisthost.local.lan : Non-existent domain

** translated from French to English.

Ok can you try from tools diagnostic > dnslooukp ?
My client linux , using pfsense resolver read a correct response , but pfsense from diagnostic tools no .

@Gertjan dns default is localhost 127.0.0.1 and root server
