Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.
How it works
Ping operates by sending Internet Control Message Protocol (ICMP) Echo Request packets to the target host and waiting for an ICMP Echo Reply. The program reports errors, packet loss, and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard deviation of the mean.
Common Uses
- Testing Connectivity: Verifying if a specific server or website is online.
- Measuring Latency: Checking how fast data travels to a destination (lag).
- Troubleshooting: Identifying network issues like packet loss.
