Ping

Send ICMP echo requests to any hostname or IP address and see real-time results.

What is ping?

Ping uses ICMP (Internet Control Message Protocol) echo request packets to measure round-trip time (RTT) between the server and the target host. Each packet travels to the target and back — the time taken is the RTT in milliseconds. Low RTT indicates good connectivity; high RTT or packet loss suggests network congestion or filtering.

Note: some hosts block ICMP traffic by firewall policy, causing 100% packet loss even though the host is up and serving other traffic. This does not necessarily mean the host is unreachable.
