Would two computers connected to a network share the same IP?

Question

Let's assume there are no IP-masking techniques being used. Just a regular network, the wireless type that people might use at home to share an internet connection.

Answer 1

you'll have the same broadcast ip for each computer. Outside your lan everyone will see all the computers as having the same ip address. Whithin the netowork the router will act as the gateway to the internet and assign local ip's for every connected computer individually

Answer 2

IP's are not really assigned to computers persay... they are assigned to network devices. If a computer has multiple network devices, it in essence has multiple IP's by the way you are thinking of it. Anyways, both computers will have different IP's assigned to their wireless network card devices, but because of the way a network works with internet connection sharing (that is, computers make requests to the router and then the router sends request and is really just passing messages back and forth between the internet and computers on network), all computers on your network will be seen as having the same IP on the internet. This won't generally cause problems though, for a certain thing that I can't explain cuz I'm no expert in computer networking lol.

Answer 3

The answer is yes and no. On the Local Area network they will have different IPs typically 192.168.1 and so on. The internet gateway will take data packets from the different local IPs and send the packets out as one WAN IP So from the internet it will appear as one IP address but can actually be many different computers.

Answer 4

No, you'd have one set for something like 192.168.1.2 and the second for 192.168.1.3. 192.168.xxx.xxx are called Class C IP#'s that are not valid on the internet, but are valid on a local network.

The wireless router would be connected to the internet and would have a valid internet IP# provided by your ISP. But on the otherside, your wireless router would also have a class C IP# on it, probably 192.168.1.1 . You would access the wireless router's configuration via webpage by going to http://192.168.1.1 (or whatever your router's default IP# is). The router then acts like a DHCP server and automatically assigns the Class C IP#'s to your other computer.

So when you access a webpage, the request is sent to the router and then the router talks to the internet. You computer's with the Class C IP's actually never talks or is recognized by the internet, the router does all of that.

Answer 5

No. Never. If another computer comes on with the same IP address as one already on the network, usually neither will work. Each of the computers on the network must have their own IP address.

Answer 6

No. Each computer has a unique MAC adress. If you are trying to escape tracing, switch internal network cards in your computer, steal an internet connection, and hope like hell no experienced employee looks at the neighborhood cable box anytime soon. Employ some serious 1334 hacking skills. Take your pick.

Answer 7

That can only happen if one or both of the computers have the IP set manually. And if that happened the 2nd computer to boot up would give you an error message about another computer having the same IP address. If they are both set up for DHCP, then no it can't happen.

Answer 8

no..they cannot share the network using the same IP address, think of it as two people trying to eat the same hamburger..
neither one of you get the whole package..

Each system needs it's own Unique IP address.

you would see packetloss on that network..
also windows would throw up a nice nastigram on both machines complaining about the other machine's MAC address.

Answer 9

Data sharing is possible between 2 computers withourt IP Adress. But for sharing internet or accessing internet u must need ip adress

Answer 10

Each computer has it's own Internet Protocol (IP) if the computers are linked to a router I believe they share the routers protocol.
