A poorly configured DNS server can slow down your connection and prevent websites from opening. Some malicious DNS servers can also cause popup ads, website hijacking (man-in-the-middle attacks), eavesdropping and a whole range of security problems. For fast, stable browsing, we have deliberately collected reliable free public DNS server addresses from around the world.
This tool belongs to the “Network diagnostics” category.
Your input is processed locally in the browser whenever possible. We do not store it.
Checks originate from our own data centre, so the network path differs from yours. Differences are normal for cross-border results or carrier-level caches.
The target may block probes, rate-limit them, or serve only certain regions. Retry with another tool or at another time.
No. Loopback, private and reserved ranges are refused so the tools cannot be used to scan internal networks.
