IP address, I don't understand

As far as I know every computer has a unique IP address, that's what my brother told me. But when my sister checked my IP address online, she said we have the same address. And we also have problems downloading from Megaupload and Rapidshare. Because sometimes it would say download exceeded because I'm already downloading a file, even though I'm not. So I'm thinking maybe it's my sister, since we're sharing the internet through a router. But then, she's not here anymore, but still those websites still display those download exceeded message. Could it be possible someone's hacking through my unit or something? I really don't understand anymore. I hope someone could help me understand.

If you use the same router it shows just one IP to the site that checks it. Even if you have a hundred computers connected. It would only show the first computers IP. If you are a student at a university and use the university computers or route through them from you private home, it would still just show the university server's IP, lol. Clear cache and cookies, that may help your download problems. Speed is also a problem. Sometimes you get that message, when your download speed is too slow.

that can be a problem with referral programs and such-they won't accept multiple users at the same address..

Oh. If I won't receive payment in some of them, then I'd know why.

well its 100% correct that each computer(system or router) which is connected to interent has unique ip address. as your are not directly connecter to inteernet , being you are connected to router which is directly connected to internet so its router which has unique ip address and all the computer which are connceted to that router all have same ip address what the router have .... so your ip address and your sister ip address will be the same as both of you using same router to connect to internet ... as far as your download exceed problem is concern .. check out whether your router have "key authorisation" is setup or not for connceting to it .. if not then may it is possible that other computer can utilize your internet .. so do first thing activate key authhorization .. its like a password to connect to your router to access internet ..... an offcourse if your sister is using then you must see thi as you have same ip address ... think this will help you out .. have a nice day...

Thanks. That was very helpful. We do have key authorization. Because whenever my cousin visits with her laptop we have to ask my brother to connect her to the internet. But right now no one else is using the internet except for me, but I still can't download. Maybe it's what others said about cookies. I'll try it out. Thank you so much for your help. I understand a lot now.

IP address stands for internet protocol .its a unique way to identify your computer in network.LIke your telephone you have a specific phone number from which any one from any where in the world can communicate with you.in the same way ip address identifys you .no two computers can have same ip address

That's how I understood it too. But they say if you have a router the router would generate it's own IP address and everyone connected to the router shares that one address.

I know when you're using same router sometimes it connects as one IP address as I know but I am not sure. I have this issue with my online pool friends wherein they can't report because they have the same IP address but the thing is they live in different countries and they haven't even met each other personally just on online pool. Anyways that one is unexplainable. I don't think you're being hacked though.

Thanks. I'm glad of the idea of not being hacked. But it's weird though to have same IP address with someone from another country. How did that happen? How did they solve it?

Individual computers do generate their own unique IP adress, but you almost answered your own question. When connected to a router, the router generates its own IP address so anyone you share a router with will have that problem. My fiance and I have that problem with MUDs also but usually if we inform the admins, they clear us to play together. Not sure what to do about your downloading thing though.

Thanks. Well, I didn't know that when connected to a router, the router would generate it's own IP, and that everyone connected to it would have the same IP address.

its possible to have the same IP address specially if you had shared a router...it happened to me and i wasn't able to access the internet because of that..i called my technician to fix it for mer..most likely we just refreshed the router to detect a new IP for each computer

Hmmm, I don't know how to do that. And I can't call a technician, I don't have money to pay him. hehe. Thanks anyway for sharing your experience.

You can share IPs with more than one computer. Its very common in many areas where the Internet providers give many connections with the same IP addres. Your case is also very common. You said you have problem with the message "you are downloading something with this IP and have to wait until this download completes". After all they are just machines and they sometimes err. Just clear your cookies and try again. The best method is to unplug and plug your Internet cable. This will solve the problem.

I have cleared my cookies and I can download again. I would try unplugging my internet next time. I hope my brother isn't using the computer when I do that. hehe. Thank you.

Ya you are right that every computer has one active network interface and so one unique ip address to the network.But your ip address my change every time you startup your system. There are some tips to fix your ip address and change your ip address if there is no ip address collision in your LAN.

ideally IP addresses are different for all users. but if same router is used and that is divided into many users, you can have the same IP address.
