if i run virtual machines on my desktop is it possible to set them to have different ips than the host pc itself
 
Most Virtual Machines such as VMware allow you to bridge the virtual network adapter to the physical network adapter which allows you to assign an address in the range your physical adapter uses. You also get the option to set up a NAT connection or Host Only connection. NAT will use a different address range than the physical adapter and just NAT the virtual adapter address range to the address on the physical adapter. Host only will setup a network range that cannot communicate to the physical network.
 
tbh that confused me quite a bit im not entirely sure this is the best way to do it. what i am wanting to do is play a game from different ips. only one account is allowed per ip, so rather than having multiple pcs i was wondering if i could use virtual machines

You have to assign different IPs the different NICs.

I think you are asking if you would/could have multiple internet facing IPs. The answer is yes, if you have multiple internet IPs provided by your ISP. By default, most ISP's only provide one IP. But I think you can get a second one from comcast for $5-$10 per month.

So yes, you can cheat at online poker.
 
no it is not poker lol its just an online game so graphics wise there will be no issue
 
I think simplesam is right, adding another virtual machine/IP won't work. Test it out by just trying to play the game on 2 separate computers behind the same router. Everything that leaves your house uses your public IP from your ISP. So even if you have 2 unique private IPs behind the router, as soon as they pass the router they will both appear to have the same IP with different MACs. So I would try it with 2 comps before doing any new config.
 
u can use multiple pcs and that works fine, just cant have multiple accounts running from the same pc simultaneously
 
you cant have multiple accounts running? or you cant open more then one instance of the game at once? try enabling windows fast user switching and just switch back and forth between users. me and my friends used to do that all the time while LANing diablo.
 
The game can't tell your IP address, they all appear the same from the outside. So it's not a problem with changing your IP.
 
Unless your ISP has assigned you multiple public IP addresses, yes it does. Read up on NAT and private/public IP addresses. Once it passes your modem, there is no way for anyone to tell what your computers IP address is. So it is not preventing the connection because of the same IP.
 
Inside your "internal" network, you are correct. You would end up with IP address conflicts causing the devices to fail to communicate on the network.

However, when using multiple PCs in a home to access the Internet, all your traffic from those PCs has to pass through the router and then the cable modem/dsl modem.

Most home-user Internet accounts from ISPs give you one IP address (using DHCP which randomizes the IP address from the ones granted to the ISP) and assigns it to the router that is connected to the cable/dsl modem.

When a PC attempts to communicate with the Internet, becuase all traffic is being passed through the router, to the Internet at large all PCs in your home network have the same IP address.

For example, open your browser to http://www.whatismyip.com/ and notice your IP address. It is going to be different than the one that is assigned to your computer on your home network (open the command prompt and type "ipconfig" and then press enter). Now go to one of your other devices and check your IP address at whatismyip.com again and it will be the same as the first computer.
 
That is irrelevant once the packets leave your network. Your router removes your private IP from the packet and puts your external IP in its place. From outside of your router, the only way to even tell you are talking to 2 separate computers is by the MAC address. So Im not sure what is preventing you from running 2 instances of the game, but it is most definitely not your IP address.
 
Bridge mode is usually what you want. Think of it as the VM being a physical machine plugged into the same switch as the host. Nat creates a virtual NAT router and the VM is behind that nat. That has it's uses, but can get more complex. If I need a NAT I usually like to just build my own NAT device in a VM for better control.
 
Depends on the game's use of your IP as a "unique" user identifier

if its an ONLINE game; SOL unless you get another external IP

if its an OFF-LINE game (internal network only; VMware player > open network manager bridged mode.
