Odd non-player IP's connectting?

[britefire]

Me and 3 friends are running a small tekkit server, nothing special. However looking at the console, I noticed a lot of abnormal overload errors, never noticed them before. They started two hours after I disconnected, and lasted about 27 minutes, and stopped when another ip (not any ip of anyone on the server though) lost connection.

Looking through the logs more, I found many instances of this ip (201.130.246.49), on many different ports, losing connection, but never actually joining the server.

Uploaded a few lines around the end of the log (http://pastebin.com/jqQaYTu2), the only two plugins running are essentials, essentials spawn, and treeassist.

Anyone know if this is an issue, or some odd side-effect of a plugin?

The IP is a Brazilian DVR Viewer, or remote surveillance system.

It must be someone trying to log on to one of their cameras, and they accidentally added your server.

Alright, thanks, glad its nothing really to worry about!
