Yes. Could be.
But first of all we have to know, which IP you meant with my_ip? Is it a LAN IP (like 192.168.1.2), do you have a LAN, or is it a public IP (assigned by your Internet Provider), and if it is a public IP, how is your PC connected to the internet? Directly? Via router?
And whom do you mean by "someone else"? Someone else in your LAN? Someone else out there in the Internet?
You see, you applied very poor information - as less as you apply, as less the chance of getting help.
