I noticed frequently that some site say that I already visited it... Or that I am currently online, or some other strange stuff like that...
I guess that someone is also using the same internet IP as my network, or someone is on my network... How I check all computers using that same IP? (or computers on my network... or... you get it :P)
EDIT: Clarifications: I know the internet IP is random, what I mean is that those "sharing" sites for example (like rapidshare, megaupload, whatever...) may say that my IP is already downloading something. Or when connecting to a IRC network, it may block my connection saying that I am a "clone" (the term some IRC networks use for someone connecting several times).
My network structure: There are a radio antenna that grabs the internet from the ISP, they don't allow me to fiddle with the modem... Then a router distributes the internet using both wireless and cables. I guess either the ISP is sharing that IP with several people, or someone is tapping on the wireless.
Yes, I know all that already, my questions is how I figure WHO are connected, and in what level? – speeder – 2010-08-10T23:24:45.683
You can log into your home router/gateway by entering the IP address of your default gateway into your browser address bar usually. There might be an attached/connected devices link which will tell you what is connected and if you are lucky a computer name. If there are more devices connected than you can account for, you can check the IP address or MAC address to match them up with the devices you own and block the MAC address of any unauthorized device. There is no way to get a real life name unless they use that as a computer name. There is no way to get similar info from your ISP. – user45795 – 2010-08-11T15:23:15.707
