B-horn, a little information for you. All the IPs that you listed were valid IPs, however they were used differently. To illustrate, I'll use the output from the command "ipconfig".
Most of these network protocols haven't been assigned IP addresses, but all of them can be. The unique IP of my computer has been censored because I recently used ip location services to track down all the routers between here and a server in Seoul, South Korea, and I don't want you guys doing that to me. XD

All of the "■■■.■■■.■■■.■■■" addresses were valid for Internet Protocol, but all of them have different purposes. For example, your 192.168.■■■.■■■ addresses were used for Local Area connections, and 127.0.0.1 is the network loopback address. Basically, what I'm trying to get at is that not all IP addresses are available to the public. Usually, to find out my IP I search "my ip" in Google. This will tell you what IP Google sees when you connect to them. Network Address Translators (NATs) can get in the way of communication even so, but that's a story for another day.
