"scope host" means that address is only visible to and from that specific host. Basically the the ip address "127.0.0.1" (also known as "localhost") can only be accessed from that specific host. On every UNIX machine, 127.0.0.1 is "this machine I am currently on". You ssh to 127.0.0.1 and the machine you're on will answer. It's basically it's address for itself. "scope link", I assume, would mean anything on that link can access it. And "global" would mean it's available globally on your network - but since that's a 192.168.* address it's only available on YOUR netwrok, and not the internet.
