How are two PCs ditinguished by the game if they are behind the same router?

[GTB]

I can only say 1 thing. An admin could see my wife played the game on a different computer at least. So there must be a way that it tracks something. And honestly not that interested in how it works. If it works it works..

As the other person said, if you're playing from two different PC's via a router Wi-Fi connection on both. You could tell because of what this person said. I'd have said so anyway having used a router and looking at it's main settings. The problem with people doing it, they do it to self trade Niobium ore for free to New Berlin from Tau-23 for example... multi-boxing to make easy money without paying a miner to mine them. There are other reasons it could be used for, such as re-entering a PVP fight when killed right away on another PC account in the house. You could also use it as a base owner to transfer commodities to another ship parked at base, then kill your other ship and re-spawn back at the place to keep bringing commodities back as (one way trips) each time.

Your IP is made of 4 Octets. In a home network, it'll be a Class C network, therefore only the last number can change

i.e: 77.100.12.2 - only the green number will change depending on the computer that's connected to the router. This last number is called the host. What was said above me is correct, 2 computers cannot have the exact same IP but servers may only pick up the network IP and not the host IP.
