I tried various searches for this and fear that I may not have my networking lingo down so I apologize in advance if this has been answered or asked. I have been using a Time Capsule as my router for almost 3 years. I have a lot of devices that use it. Between TiVo's, Printers, Home MacBooks, Work Laptops, there are usually 10-15 devices with active wireless network connections. I noticed that my ip addresses are always 10.0.1.x where x is always in the 2-15 range. This week I saw that my Sony Google TV was 10.0.1.27 and some devices are up into the 30's. This isn't affecting performance but I am curious as to why the IP's have suddenly risen. Right now I have (according to IP Scanner App and Airport Utility) 10.0.1.4 10.0.1.6 10.0.1.12 10.0.1.14 10.0.1.18 10.0.1.20 10.0.1.22 10.0.1.23 10.0.1.24 10.0.1.25 10.0.1.27 A week ago this list would have been 10.0.1.2 through 10.0.1.14 (or something like that). Is this anything I should be concerned about? If not, I am just really curious why this numbering changed after 3 years.
