Not necessarily. His ISP might use Dynamic Host Configuration Protocol. If his ISP's network was down, he may have been designated a new IP when it came back online, which would mean his original IP was now free and could've been designated to another PC on the network.
Maybe.. But what are the chances of two separate users having the exact same IP address if not from the same computer?
They simply have the same Internet Service Provider. I don't think you're following me.
Say we have User1 who registers, here. Their IP address is logged, accordingly. If this user's ISP uses DHCP, and the network goes down, they are re-assigned a new IP when service comes back online, thus freeing up their original IP. Or maybe they cancelled their service. Again, their IP is now free to use with another customer.
Now we have User2 who comes along and begins using the same ISP. This user is designated a new IP address. Since User1's old IP address is free, the ISP could now assign it to User2.
Understand?
But I logged in by different computers everytime that I post in this forum. Wouldn't it conutine to change the Internet provider address every time?!
