MacOS - bash script to change IP settings

I work in organisation with paranoiac system administrators...
Every morning on my work i have to change IP settings on my Macbook manually.
Plus every week they send new IP address, gateway, mask.

And this is annoying.
So i made simple script that starts every time i came on work and back home/cafe/etc.
If someone have same problem or something like that, here it is:

[code]
echo “home or work?”
read ipconf
if [ $ipconf = work ]
then
networksetup -setmanual Wi-Fi 111.111.1.111 255.255.0.0 111.111.1.112
echo “Work settings applied.”
fi
if [ $ipconf = home ]
then
networksetup -setdhcp Wi-Fi
echo “Home settings applied.”
fi
[/code]

You can call it from terminal:
bash ip.sh
(in my case ip.sh - file name)
