I have notice a signification data usage on my pi even when I am not using it. this can be a problem as I am using a IOT sim card with a small cap.
I have setup iftop and monitored the traffic for a couple hours. here are few of the connections my pi had that I have no idea why. during that time my was not supposed to anything.
- ntp15.doctor.com
- vf1.bbnx.net
- y.ns.gin.ntt.net
- 129.250.35.251
- 10.177.0.210
- cloudflare.com
Would anyone be able to shed some light on those connections and confirm if those might be reason for the high data usage.
