Hi,
It is a stupid idea if you ask me,
..and thus, based on most of the current technology patents out there, perfectly patentable. dont worry, the rest of the internet will probably need something like this in the future... and whats happened here is some coffee-room tech chat or water cooler propeller-head conversation got captured and written-up by some over-zealous manager/techie combo to ensure that the world cant do something obvious later when needed (its probably not obvious to most people righ tnow as we havent even bothered looking at it...but if we did then it would probably be an obvious method and first one out of the wash). when it means is that most of those ISPs that do a captive portal answer for failed DNS responses are going to be violating this patent if the query was for IPv6 and didnt get an answer..... ;-) alan
