Try running a Ping Plotter (
www.pingplotter.com free version at the bottom of the download page) to 206.16.60.38 for a few minutes, immediately after a disco, and see what it shows.
If you cannot fathom what you are looking at, feel free to email the text version or a bitmap of the results to me and I will be happy to take a look at it, or you can post it here.
