I'm using it for online games and running programs for friends out of one PC. Limits will be placed soon, so my question is: how can I get a different IP address for each account loading up from one single PC. If they place a limit of two logins from one IP address, then we would need to run 10 logins from one PC, all with their own IP address.

Can this be done reasonably cheap?

Contact your ISP to understand the costs of this. – Ramhound Feb 4 '14 at 17:15
Talk to your ISP. Some of them offer plans that include multiple public IPs. Alternatively, you can look into a VPN service or make one yourself with an EC2 instance (or other VPS). – David Schwartz Feb 4 '14 at 17:15
what exactly do you mean 10 logins? you mean 10 windows logins? 1 pc is going to have 1 ip address. – Sickest Feb 4 '14 at 17:59
Not much of a tech person for PCs, but VPN won't work, those providers say I need to go Private Proxies. People needing this will only be able to login two accounts per IP address to the game. Most players now hold 10 to 40 accounts, which means that every two accounts will need their own IP address..... – Darrell Feb 4 '14 at 19:33
It will be prohibitively expensive. – user294732 Feb 5 '14 at 2:13

Typically you assign one IP address to each interface at a time. If I understand you correctly, you want to run 10 IP addresses at one time. That means you need 10 NICs which is rare for a desktop machine. Not to mention, your ISP will probably require you to get a Business Class service from them in order to get multiple public addresses through them.

Long story short: You can't easily do what you want to do, especially if you want it cheap.

You don't need 10 NICs to have 10 IP addresses. – MaQleod Feb 13 '14 at 16:21
True, but typically you do. – Alex Feb 13 '14 at 18:07
Why? I always just put them all on the same NIC, unless of course I need to worry about bandwidth - but if I'm reading/writing so much that I am over-powering a PC NIC, I'm probably beating the processor or HDD to death, so having multiple NICs would just be pointless. – MaQleod Feb 13 '14 at 18:18
