View DNS cache (using MacOS Monterey version 12.6.5)

Is there anyway to view the DNS cache on Mac? All the information I've been able to gather so far online has led to a dead end.

The most common solution I find is this one:

Open up the Console and search for any:mdnsresponder and press "Start"
Open up Terminal and enter sudo killall –INFO mDNSResponder
Go back to Console to see DNS records

However, I do not see any DNS records in the Console. Instead, I see record of mDNSResponder activity, but not DNS records themselves.

In fact, I have seen this message a few times: Sending SIGINFO to mDNSResponder daemon is deprecated. To trigger state dump, please use 'dns-sd -O', enter 'dns-sd -h' for more information.

Anyone have any thoughts?

sudo dns-sd -O

XPC service returns error, description: State dump is only enabled in internal builds

but if you are looking for dns record for certain fqdn you can use

sudo dns-sd -G v4v6 captive.apple.com
