172.23.104.73 is DNS resolver in my home office VPN (Cisco AnyConnect) for my MacOS.
On a linux server at my work I also see a good response with 172.23.104.73 as DNS resolver:
๐ง [email protected]:~$ s ./dnspeep
query name server IP response

Without VPN my local DNS resolvers 192.168.0.1 or 192.168.42.241 (in different home-Wifis) are used on MacOS and responses are good:
