IP Lookup Tools Global Reachability Test

Global reachability test

Check an address from different countries with ping, traceroute, MTR, HTTP, port and DNS. Measurements are sent from your browser to the Globalping network.

Example: example.com, 1.1.1.1 or https://example.com

What is checked?

  • Ping: latency and packet loss from each location
  • Traceroute: the path to the target from each location, with hop addresses and latencies (ICMP or TCP)
  • MTR: packet loss, latency and jitter per hop from each location
  • HTTP: status code with DNS, TCP, TLS and first byte times; response headers and the TLS certificate (is it the same everywhere, when does it expire)
  • Port: whether a TCP connection to a single port can be made
  • DNS: the answer each location's resolver returns for the record type you pick
  • Worldwide, Türkiye, Türkiye home and ISP lines, Europe, North America, Asia or a country you choose

How do I read the result?

  • Responding: the location reached the target. Partial response: some packets were lost. No response: none came back.
  • If only one location fails, the problem is usually that location's network rather than the target, or the target blocks that region.
  • Traceroute: hops that do not answer at the end of the path are often a firewall; the target may still be working. For sites that block ICMP, choose the TCP protocol.
  • MTR: loss shown at one hop but not at the following hops is usually the router limiting its replies, not real loss; only loss that continues to the end of the path is real.
  • Certificate banner: green means every location sees the same certificate. Yellow means the certificate expires in less than 30 days or the certificate differs by location; red means it has expired or is not trusted. The button on a row opens that location's headers and certificate.
  • Probes are mostly data center lines; to see home and operator lines use the Türkiye home/ISP option.

Frequently asked questions

Who runs the measurement?

Probes on the Globalping network. Your browser starts the test; our server does not generate the measurement traffic.

Are the results public?

Yes. Globalping stores the target and the result publicly, and your IP address reaches Globalping when you run a test. Do not test a private address with this tool.

Why does the certificate differ by location?

Some CDNs serve a different certificate depending on the location or client; if the issuer and expiry date match, it is fine. If old and new certificates show up together on one address, the rollout after a renewal may still be in progress.

How do I share a result?

Once a test starts, the link in the address bar points to that measurement; you can take it with the Copy link button. Whoever opens the link sees the same result without running the test again; Globalping usually keeps results for up to six months.

Why is my hourly allowance limited?

Globalping gives each visitor IP address a limited number of probes per hour, and each location counts as one probe. Your remaining allowance is shown after a test, and when it runs out you see when it reopens.

Why does it not tell a closed port from a filtered one?

If a TCP connection attempt gets no answer, the cause can be a closed port or a firewall. The tool shows both as unreachable.

Who provides the Istanbul measurement point?

A server sponsored by Orfi (Netvia Bilisim). It is a probe joined to the Globalping network, it takes part in every test when "Türkiye" is selected and carries a "Sponsor: Orfi" label in the results. Link: orfi.net.tr
