[mssms] SCCM collection creation by script

[Jason Wallace]

Hi folks
 
A dumb question for this morning but . . . 
 
I am in the midst of a 2007 - 2012 migration.  We want to move devices over by 
IP subnet as there are a large number of branch offices.
 
I wonder whether someone has a magic script that can allow us to read the 
default gateway from hardware inventory and then create a series of collections 
on that please?
 
Thanks
