One random use I found years ago was that I could instantly search for Comcast business boxes and then export the IPs as a csv, run a headless browser script to try default login creds, then scrape the wireless Mac, ssid, and password which I could plot on a map using wigle wifi wardriving data. It's pretty cool. Maybe the monitoring service will come in handy if it ever notifies me of anything I should be concerned about on any of my IPs, hard to turn down a $5 lifetime pass.
