Control apple network profile from the command line

I have to change between a network with a fixed address setup and some others with dhcp quite often, so i was really glad i found out about networksetup. The following snippet switches from the static to the dhcp profile, both of which i defined earlier in the network settings.

networksetup -setnetworkserviceenabled static off

networksetup -setnetworkserviceenabled DHCP on

This is a real time and sanity saver!
