Test network latency, packet loss, and connection stability
Ping is a network utility tool that tests the reachability of a host and measures round-trip time for messages sent from your device to a destination computer.
Ping Tool is a free online utility that tests the reachability of a host on an IP network. It measures the round-trip time for messages sent from your location to a destination server. This is essential for diagnosing network connectivity issues and measuring latency.
Our online ping tool lets you check if a website or server is online, measure response times, and identify network problems without installing any software.
Measure round-trip latency in milliseconds to diagnose connection speed issues.
Verify if a server or website is online and responding to requests.
View packet loss statistics to identify network reliability issues.
Ping both domain names and IP addresses to test connectivity.
Ping sends small packets to a host and times the round trip, so it answers two questions at once: is this host reachable? and how fast and reliable is the connection to it?
Ping tells you whether and how well you reach a host; when it's slow or lossy, Traceroute shows where along the path the problem starts.
Ping measures the round-trip time (RTT) it takes for a small data packet to travel from your device to a server and back. It also indicates whether the destination is reachable and responsive.
A ping under 20ms is excellent, 20-50ms is good, 50-100ms is acceptable, and over 100ms may cause noticeable lag. For gaming, lower ping is crucial for real-time responsiveness.
Ping can fail if the server is down, ICMP packets are blocked by a firewall, there's a network routing problem, or the domain doesn't resolve. Many servers block ping requests for security.
Everything this tool does, available as a simple REST endpoint with JSON responses — perfect for scripts, monitoring and integrations. Free tier: 100 requests/month, no card required.
