If we execute the -getinfo flag again we can see the details listed under DHCP Configuration. This flag is specifically for IPv4 configuration, and for IPv6 we can use the flag -setv6automatic. Now lets configure the interface to use DHCP, by running networksetup with -setdhcp flag.

If the IPv4 configuration is off there will be no info listed under DHCP Configuration, and IPv6 will show the current status accordingly.

We can get the status of IP configuration by running the networksetup command with the flag -getinfo. networksetup -getMedia 'USB 10/100/1000 LAN' Once the cable is plugged in Active: in the command result will show the bandwidth and duplex. If the cable is not connected result will say Active: none. The -getMedia flag will tell us whether the physical cable is connected or not, make sure the “M” is uppercase in Media. In my case I’ll be using Hardware Port: USB 10/100/1000 LAN and/or Device: en6 networksetup -listallhardwareports The -listallhardwareports flag will list all the connectivity related hardware available on Mac, run below command in Terminal to identify the network interface. Even though there are references to IPv6 commands, we’ll be completely focusing on IPv4 configuration. Let’s look into few core basic commands that we can use. There are 100+ flags or subcommands available with networksetup to assist with viewing or changing network configuration. The networksetup command is used to configure network settings typically configured in the System Preferences.

set IPv4 DNS manual – networksetup -setdnsservers interfaceName dnsServer1 dnsServer2.

set IPv4 manual – networksetup -setmanual interfaceName ipAddress subnetMask gateway.

set IPv6 automatic (DHCP) – networksetup -setv6automatic interfaceName.

set IPv4 automatic (DHCP) – networksetup -setdhcp interfaceName.

turn off IPv6 – networksetup -setv6off interfaceName.

turn off IPv4 – networksetup -setv4off interfaceName.

get the list of network interfaces – networksetup -listallhardwareports.
