    Ever wondered how to change the MAC address on your Macintosh and set up a static IP address? Place these few lines to AppleScript editor and change the addresses (mac/ip/mask/gateway). After running this script you can check whether it is working by running "ifconfig" from your console. The "en2" points to a USB to Ethernet converter, in my case I am using Macbook Air with usb adapter. By running the ifconfig command the system will show you a list of all network adapters, so choose the right one and replace the "en2" with the adapter you want to set for static address..

do shell script "ifconfig en2 ether 00:17:31:ac:33:13" with administrator privileges
do shell script "ifconfig en2 147.175.183.86 netmask 255.255.255.0" with administrator privileges
do shell script "route add default 147.175.183.1" with administrator privileges
do shell script "ifconfig en2 down" with administrator privileges
do shell script "ifconfig en2 up" with administrator privileges
