Ok, I was just wondering...If I have 3 computers/laptops etc. and they are all connected to the same router to access the internet, does that mean all of the computers have the same IP Address?

Or will each computer have a unique IP Address?

Sorry if this is an obvious question, I think I already know the answer, but just want to confirm I guess

    The same. Your router is your face to the world.

    All computer have same IP.

    your modem is single and you connected with router that's a making sense your modem is supply net to the router so that's your IP.

      Do their internet speed will divided into three? or each computer has same internet speed..
      If all three are downloading a movie at the same time you will have congestion, but with normal use no one will notice anything. At one of the sites I managed I set them up with a DSL connection while we waited for their T1 to be installed. 24 people shared it and no one had any complaints at all.

    Each computer has its own unique IP address on an internal private network. The internal private network as a whole has its own unique private address and then information is routed to the correct address by NAT routing. Routers have their own DHCP service (this is what hands out IP addresses) for their internal networks. NAT (network address translation) allows for proper routing of information from the internet to the correct IP address on a private network.

    The responses were a LITTLE unclear.....

    The computers have DIFFERENT IPs TO THE ROUTER! On the internet, they will all look like the IP assigned to your connection by systems you are connected to. ALL will appear to have the SAME IP on the internet.

    The speed, assuming it is over the transmission speed of the connection(s) to the server(s) or router(s) it is hooked up to, will AVERAGE the highest speed of the input, unless that exceeds the speed of the output.

    SO, if you are connected to a server putting out 100Mbps, and your router has an input of 100, and an output of 10, and one thing is hooked to your router, you get 10Mbps! If the output maximum were 100Mbps, you would get that. If 3 connections are connected and receiving at the same rate, the 10Mbps connection would give ALL 10Mbps(3*10=30 which is less than the 100 it can accept and is fed). If the three connections where 100Mbps, each could go up to 100Mbps as long as the aggregate wasn't over 100. So 30,40,30 or 10,80,10 or 10,20,70, etc....

    As long as I am at it, the standard baset IS a collision detection system(Basically, if 2 connections try at the same time, they wait a random amount of time, and try again) which means multiple connections will RARELY total the one comming in, but that is something you can't really predict.

    Thanks for all the information everyone!

    CONCLUSION? - Every computer has its own unique IP, but if each computer is using a router to access internet, then it is the IP of whatever is connecting to the internet (The router in this case) that shows. So if 10 computers were using a wireless connection to a router for internet access, they would all be shown as the same IP in the online world.

    I think that clears it up, rite?

    Thanks All

    Nope. To be technically correct, all your computers have the same public IP and not the private IP and I presume you are using a single IP broandband solutions. The private IP must be different otherwise all your computers will NOT able to connect to the Internet,

    It is done by the router via a NAT translation which translates usually 192.168,x,x IP to the Public IP provided by your ISP.

    I know it is a bit technically but it makes what the Internet works today.
