About Pingr

Pingr is a small set of network diagnostic tools built around one idea: ping. Not monitoring, not alerting, not a dashboard — you ask a question, you get an answer, and nothing is stored.

The two kinds of measurement

Almost every confusion about ping tools comes from mixing up two different questions, so Pingr keeps them on separate pages and labels every result with which one it answered.

  • Pinging a target. Ping Test, IP Ping, Website Ping and Ping Port all run from Pingr’s server in Ashburn, US (ash). They tell you about the path between that server and your target. They tell you nothing about your own connection, which is why every one of their results says so in as many words.
  • Measuring your own connection. Internet Ping Test runs entirely in your browser, against the nearest Cloudflare edge. It never touches our server.

PingrBot

When Website Ping fetches a page, the request identifies itself as:

PingrBot/1.0 (+https://pingr.com/about)

If you have found that in your logs: it was one GET request, made because a visitor to Pingr typed your domain into a reachability checker. It sends no cookies, no authentication and no request body, follows at most three redirects, and reads at most 32 KB of the response before closing the connection. It does not crawl, it does not follow links, and it does not come back on a schedule.

If you would rather Pingr did not test your host at all, write to abuse@pingr.com from an address at that domain and we will exclude it. See the abuse page.

What Pingr refuses to test

Private addresses (10.x, 172.16–31.x, 192.168.x), loopback, link-local, carrier-grade NAT, multicast, reserved documentation ranges, and cloud metadata endpoints such as 169.254.169.254. Hostnames ending in .local, .internal, .lan, .corp and similar are refused before they are even looked up.

If a hostname resolves to a mixture of public and private addresses, the whole request is refused rather than the public one being used — that pattern is a DNS rebinding attempt, and picking the “safe” record out of a mixed answer is exactly how tools like this get turned into a way to reach inside somebody’s network.

Rate limits

There are limits per visitor and per target. If you hit a visitor limit you will be asked to complete a quick verification and can then carry on — you are not blocked, because a great many people share a public address with thousands of strangers, and blocking that address would punish all of them for one. Limits per target are firmer, because those exist to stop Pingr being used to bother somebody else.

Data sources

IP details come from a locally bundled database. Depending on the deployment this is either MaxMind GeoLite2 or the IPinfo free country and ASN bundle:

  • This product includes GeoLite2 data created by MaxMind, available from maxmind.com, licensed under CC BY-SA 4.0.
  • IP address data may be provided by IPinfo, used under their free-tier terms with attribution.

The lookup is local, so it adds no external dependency to the request path and no third party learns what you looked up.

What Pingr is not

There is no uptime monitoring, no scheduled checks, no alerting, no accounts, no saved history and no dashboards. Those are real products and this is not one of them. Pingr is the thing you open when you need an answer right now.
