All, I'm not sure that this applies to all networks (mine is COX) but I thought just a quick word of caution might be in order about attempting to enumerate and "play" with IPs associated with cable modems. My modem on the service provider side has an IP address in the 10.x.x.x range. My concern here is that so does my digital cable set top box. Play around with the various IPs and you might end up nuking the set top programming of your neighborhood Just a thought - as I have not attempted this yet.
