Problem this snippet solves:

This PowerShell application will query the system wide IP based statistics and display them in columnar format.

This is a second part of a series on system based statistics. The first example was the PsSystemHttpStats example which covered a rollup of all the HTTP profile statistics. This example will present the aggregated low layer IP based statistics.
