In this video, we take a look at a macOS terminal command that will allow us to query forward and reverse lookups on a local DNS server. This command can be particularly handy when testing a DNS server that you have installed onto your local network.
Note: As Network Utility was deprecated in macOS 11, we recommend that you use this command when testing the configuration of a DNS server on a Synology NAS.
Quick reference notes:
- From your macOS desktop, select Spotlight Search.
- Within Spotlight Search type Terminal and press Enter on your keyboard
