Connecting two computers to ISP with different IP addresses?

Question

So i want to have 1 computer running a different public ip address ( the one the internet sees) then another computer. So basically two computers connected with the same ISP but with two different IP addresses. Is this even possible? Will I need to connect two routers or two switches? will that even make a difference?

thanks

Answer 1

I'd agree with catherine you do need to provide more details.



If you say a public ip as "the one the internet sees" then you have to be specific that have you purchased that public ip as your isp will always nat your ip with its own public ip pool.



If you have two computers with the same isp, they can be at a single location in which case you do not need to involved your isp and set them up in your own home network. They will still have different ips and will be connected to the same isp.



If they are at different locations (Assuming you don't have purchased a public ip for neither of them) then you will have routers at both places connecting them to isp so you can setup a VPN connection between them using a software like team viewer.



If you have purchased public ips for both of them you can just use Remote Desktop Viewer or Run/mstsc in windows to connect to the other computer in windows, if you are running linux you may need to install vnc or rdp clients but you can use ssh without any additional software. just go to terminal type ssh and the ip of your other computer.



I am not trying to insult your intelligence here by giving so many options many of which you would be already aware of, its just that i have no idea of the issue you are facing and what do you have right now. So please elaborate

I don't understand really what you mean but bottom line is that your ISP will not allow you to have two modems/routers running in your home for simple reasons.



What you can do is subscribe to a proxy server for a set amount a month. That way both computers will be connected but they'll have different IP address because the one connected through the proxy is connected through an IP address somewhere else around the world.

Hello there.



If you have a residential DSL account your modem takes the IP address it is given by the ISP. With business DSL you can get the above with priority service if you ever go down. You can also get static IP block where you're assigned more than one public IP address. You can also order an additional residential internet account.



If you have DSL this may require additional cabling to your apartment or house. If you have cable internet you'll need a spliter where the existing cable modem is needed. Keep in mind the more splitters you have in front of the main source the weaker the signal gets.

Answer 4

Your ISP will be happy to sell you as many different IP addresses as you want, as this means you will pay them a lot more money.



Most everyone uses a router to share the one public IP address they get from their ISP among all the members of their home network, it is less expensive that way.
