Script for change IP static address using Powershell

Hi...

I have a question: I regularly connect me to two different network segments, I want to know how to create a script to map to the network adapter an IP static, in this way could run the corresponding script when I find in each segment of the network using powershell... the DHCP  not permitt in company, is for that reason that I need a way to automate the allocation of IP address static in my network adapter, in this way could change the IP address depending on the network segment that I find.

I hope your comments..

Thanks
