Test IPs and Network Verification

How to Obtain Useful Test Results

1. Test once during normal hours and once during the evening peak, recording the date, carrier, and target data center.
2. Use Ping to observe latency and packet loss; if the target blocks ICMP, also consider actual application connections.
3. Use MTR or Traceroute to inspect the path; do not judge the entire route solely by packet loss at an intermediate hop.
4. Download speed tests consume traffic. Before comparing, confirm that the test file matches the target data center.
