macOS and the `networksetup` command - now I did not know that

Whilst providing some guidance to a colleague having fun with their Mac's DNS configuration, I "discovered" a new ( to me ) command - networksetup - which includes a HUGE array of useful commands: -

networksetup -listallnetworkservices

An asterisk (*) denotes that a network service is disabled.

USB 10/100/1000 LAN

Wi-Fi

Bluetooth PAN

Thunderbolt Bridge

networksetup -getdnsservers Wi-Fi

There aren't any DNS Servers set on Wi-Fi.

networksetup -getcomputername

Dave’s MacBook Pro

networksetup -getMTU Wi-Fi

Active MTU: 1500 (Current Setting: 1500)

networksetup -getinfo "USB 10/100/1000 LAN"

DHCP Configuration

IP address: 192.168.1.21

Subnet mask: 255.255.255.0

Router: 192.168.1.1

Client ID: 

IPv6: Automatic

IPv6 IP address: none

IPv6 Router: none

Ethernet Address: 00:a0:3c:37:02:42

etc.
