Fast system administrator tools

Send ICMP ping packets to any host and measure round-trip time. A basic connectivity test to check whether a server is reachable and how fast it responds.

Ping

ICMP ping for an IP or domain

1–100

What it is

Ping checks host reachability using ICMP echo. Enter an IP or a domain — the service sends several echo requests and shows latency and loss statistics.

How it works

Enter a host (IP or domain) and the number of packets (1–100). We make ICMP requests from our servers, not from your browser.

Examples

  • 8.8.8.8 — ping Google's DNS.
  • example.com — ping a domain after DNS resolution.

Limitations & notes

Even with 100% packet loss the response is still successful (HTTP 200) and shown as text. Errors 400/404/500 indicate invalid parameters, DNS failures or internal errors.

Results reflect connectivity from our server. Firewalls/NAT may filter ICMP.

FAQ

  • Why are private IP addresses blocked? Private IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) and loopback addresses are blocked to prevent the tool from being used to scan internal networks. Allowing pings to private IPs from a public web service could expose internal infrastructure or be used for reconnaissance attacks.
  • What does 100% packet loss mean? Complete packet loss usually means the host or an intermediate network is blocking ICMP traffic via firewall rules. Many cloud providers and corporate networks filter ICMP by default. A host can be fully operational (serving HTTP, SSH, etc.) while still blocking ping - packet loss does not necessarily indicate a service outage.
  • Why does ping latency vary? Latency fluctuations are caused by network congestion, routing changes, geographic distance and processing delays on intermediate routers. A transatlantic ping (e.g. Europe to US East Coast) typically shows 80-120ms. Jitter (variation in latency) above 20-30ms can affect real-time applications like VoIP and gaming.
  • What is the difference between ping and traceroute? Ping measures round-trip time and packet loss to a single destination. Traceroute shows every hop (router) along the path, revealing where delays or packet loss occur. Use ping for a quick reachability check, and traceroute when you need to diagnose where in the network a problem is happening.
