Thanks, Carol. I teach several software classes to technicians who are not all that network savvy, and this handy little tool makes my job and theirs easier.
On a related note, I also recommend my students who are forced to maintain and switch between several static IP addresses multiple times a day use NetSetMan http://www.netsetman.com/
. Again, not that it is all that much work to change IP addresses, but reducing steps is always good.
