An "Angry IP Scanner" is a piece of software which is designed to scan your network, in order to keep it more secure. It does this by monitoring any activity to all IP's and across all router ports.
Yes you very well can. All you have to do is close everything out except Tinychat, scan for ports your connected to, when you find the port you're connected to on Tinychat, scan that for the connected IP's. Very simple if you know what you're doing.
It could be your communications company, then always ping your pc. Did you get this from your firewall. There are hundreds of ip address that will scan your ports all day long. Some looking at info some trying to hack. If you want to know who the ip belongs to, just go to WHO IS, and put in the ip and it will tell you who it is registered to. If you want to trace the ip, search trace ip, and you will see several sites that will trace the ip.
to forward ports you will login to your router go to the nat function and select the ports you want to forward and to what internal ip
