All works when query with basic feature:

PS C:\Users\kldac> dnslookup www.tiktok.com 208.67.222.222
dnslookup v1.10.0
Server: 208.67.222.222

dnslookup result (elapsed 36.0885ms):
;; opcode: QUERY, status: NOERROR, id: 20377
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;www.tiktok.com.        IN       A

;; ANSWER SECTION:
www.tiktok.com. 187     IN      A       168.143.171.189

But I'm going to get error code when query with extra options:

SUBNET

PS C:\Users\kldac> SUBNET=1.2.3.4/24 dnslookup example.org tls://8.8.8.8
SUBNET=1.2.3.4/24: The term 'SUBNET=1.2.3.4/24' is not recognized as a name of a cmdlet, function, script file, or executable program.

or

So how to use extra features on Windows (11)?

On Windows the way you pass env variables is a bit different.

Try this:

cmd /V /C "set SUBNET=1.2.3.4/24 && dnslookup example.org tls://8.8.8.8"

yes there's no error. But I found SUBNET not working.

the output is 36.155.132.31 when SUBNET=1.2.3.4/24:

PS C:\Users\kldac> set SUBNET=1.2.3.4/24 && dnslookup www.baidu.com tls://223.5.5.5

It is still 36.155.132.31 when SUBNET=114.114.114.114/24:

Another example with Quad9 EDNS version:

SUBNET=1.2.3.4/24 for www.paypal.com

PS C:\Users\kldac> set SUBNET=1.2.3.4/24 && dnslookup www.paypal.com tls://9.9.9.11

same result when SUBNET=114.114.114.114/24 for www.paypal.com

Try this:

If I typed cmd /V /C "set SUBNET=1.2.3.4/24 && dnslookup example.org tls://8.8.8.8"then

C:\Users\kldac>cmd /V /C "set SUBNET=1.2.3.4/24 && dnslookup example.org tls://8.8.8.8"

Sorry, I don't have a Windows laptop to check this.

At some point in the future dnslookup will be rewritten to provide a different command-line interface, it will be better then.

Above all, thank you for developing this tool! I'm going to be happy to try futural version!
