Check if any website, server or IP address is online and measure its response time, latency and packet loss in real time.
A ping test uses ICMP (Internet Control Message Protocol) Echo Request and Echo Reply messages defined in RFC 792. Our server sends a small packet to your target host and measures the elapsed time when the Echo Reply arrives — the round-trip time (RTT) in milliseconds. By sending four packets, the test calculates minimum, average and maximum RTT, plus the percentage of packets that received no reply (packet loss). When ICMP is blocked by a firewall, the tool automatically falls back to a TCP connection probe on ports 80 and 443. Use our Port Checker to verify specific service ports are open alongside the ping test.
For competitive online gaming, under 30ms is excellent; 30–80ms is acceptable for most titles; over 100ms causes noticeable lag. For video calls and VoIP, under 150ms round-trip is generally imperceptible — over 300ms produces audible delay. For video streaming, latency has far less impact since content is buffered. To identify which network serves a game server or streaming host, use our ASN Lookup.
Packet loss occurs when one or more sent packets receive no reply within the timeout window. Even 5% loss in a voice call means roughly 1 in 20 audio packets is dropped, causing choppy audio. For gaming it triggers lag spikes and disconnections. Packet loss can be caused by network congestion, physical link errors, firewall rules, or the host being offline. If a host shows 100% packet loss but you believe it is online, ICMP filtering is the most likely cause — confirm HTTP is working with our HTTP Headers Checker or verify specific ports with our Port Checker.
Many cloud servers, firewalls and CDN-proxied domains block ICMP Echo requests entirely while allowing HTTP/HTTPS traffic. When this happens, our tool automatically switches to a TCP connection probe on ports 80 and 443. The result is labelled "TCP probe" so you know it is not a standard ICMP ping. To confirm HTTP is working on the host, check the full response with our HTTP Headers Checker. If TCP also fails, confirm DNS resolution with our DNS Lookup.
Jitter is the variation in latency between successive packets. If packet 1 takes 12ms and packet 2 takes 48ms, the jitter is 36ms. Low jitter means a consistent packet delivery rate; high jitter means unpredictable arrival intervals. This tool estimates jitter as the difference between maximum and minimum RTT. For voice and video calls, jitter above 30ms causes audible quality degradation even when average latency looks acceptable. To understand the network path to a target, look up its IP with our ASN Lookup to identify the provider and region.
Running the probe from our server provides an external, location-independent baseline that reflects what real users, search engine crawlers and monitoring systems see — unaffected by your local ISP, Wi-Fi conditions, VPN or browser extensions. This makes it particularly useful for confirming a newly deployed server is publicly reachable. To check what IP your own connection presents to the public internet, visit our What Is My IP tool.
A ping test confirms the host's IP address is reachable at the network layer. A port check tests whether a specific application service is running and accepting TCP connections. A server can pass a ping test while a critical service is crashed and its port is closed — and vice versa: a server can block ICMP (failing a ping) while serving HTTPS normally on port 443. Use ping to establish basic reachability, then our Port Checker to verify services, and our HTTP Headers Checker to confirm correct HTTP responses. Our DNS Lookup confirms the IP being pinged is the correct one for the domain.
