I recently started a minecraft server (locally, my server sits next to my desktop on my local network) and today I noticed that my 200 gb monthly limit is nearing, which is an 800% increase in internet usage.
I go to my ISP webpage, and the hourly breakdown and I can clearly see the hours that I was playing minecraft as the hours when downloads/uploads were occuring.
Does minecraft really use bandwidth unnecessarily while simply being logged in or playing? (I say unnessasarily because me and my server are both on the same network, there is no external server and no need to go outside my network).
Is there any simply solution that I can employ with my router, short of logging in to minecraft and then unplugging the router from the phone line?
