Ping Test
Check server or domain network connectivity and latency online
Enter an IP address or domain and click "Start Ping" to test connectivity
What is Ping Test?
Ping is a network diagnostic tool used to test network connectivity and latency between hosts. By sending ICMP echo request packets to a target host and waiting for replies, it determines whether the target is reachable and measures network latency. Ping testing is commonly used for network troubleshooting, server monitoring, and network performance evaluation.
How to Use
- Enter the target server address in the "IP Address / Domain" field
- Select the number of pings (1-20), default is 4
- Click the "Start Ping" button and wait for the test to complete
- View statistics: packet loss rate, average latency, min/max latency
- View detailed results for each ping: status, latency, TTL
FAQ
Q: What latency is considered normal?
A: Generally, 1-10ms within the same city, 10-50ms across the country, and 50-300ms internationally are considered normal. Higher latency means slower network response.
Q: What does 100% packet loss mean?
A: 100% packet loss means no ping packets received replies. The target host may be unreachable, the firewall may be blocking ICMP requests, or there may be a serious network issue.
Q: Why can some servers be accessed but not pinged?
A: Many servers disable ICMP echo responses for security reasons, making them unpingable. However, this doesn't affect normal HTTP/HTTPS access as they use different protocols.
Q: What is TTL?
A: TTL (Time To Live) is the lifespan of a packet, decremented by 1 at each router. The TTL value can help identify the target OS type, e.g., Windows typically uses 128, Linux typically uses 64.
