Many network administrators use the traceroute command daily. It is a convenient tool that you can use under different operation systems – Windows (Tracert), MacOS, Linux (traceroute) and even on mobile (Android and iOS).
You can use traceroute, and see the full route that the packets take to their destination (domain or IP address). Apart from that, you will see the hostnames and IPs of the routers on the way and the latency, the time it takes for each device to receive and resend the data.
You can see which gateway is discarding your data and later you can fix it.
