I've been unable to connect to several sites this last week. I have a home network, and my wife's machine can connect to the same sites, but my machine can't. And I've found that all of their addresses start with 192. For example: 22.214.171.124 Looks like a meaningful clue. Curiously, my router and cable modem both begin their internal IP's with 192. What's the significance of 192?
