Pros
With this tool, you can import large lists of TCP/IP addresses, or (say) router names from a spreadsheet and ping them all in a matter of seconds. If you manage a large router network, you've probably been looking for something like this.
Cons
This link downloads version .86 of the software, not the .96 version listed. You can get the current version from the vendors web site, although I didn't notice any significant differences between the two.
