Set IP during Task Sequence PowerShell – SCCM ConfigMgr MDT

So this Is an older script of mine that I developed for a client to receive variables from a task sequence and then assign the IP of the machine based off the variables. This specfic client set the IP variables on the actual Machine object in SCCM so that during the task sequence it would pull the machine specific IP details. Their Task seqeunce was running only ConfigMgr tasks but this could quite easily be re-used for a ConfigMgr / MDT task sequence using the custom settings or database to set the IP Variables.

As always this is as is, the usage is defined in the script header and if you do use it please remember to use the modded by field 🙂
