Traceroute (Remote Network Path)
Trace the route packets take to a host or IP from one of our servers — every hop along the way, its reverse DNS, and the round-trip time to it. Because it runs from a remote vantage point (not your device, which can't send ICMP from a browser or phone), it shows the path from the public internet to your target, which is exactly what you want when diagnosing where traffic slows down or stops.

What it checks
- Every hop on the path to the target (up to 20)
- Each hop's IP address and reverse DNS hostname
- Per-hop round-trip time in milliseconds
- Whether the destination was reached or the path stops short
- Works for both IPv4 and IPv6 targets
How to read the result
- Each row is one hop; rising round-trip times show where latency is added.
- '* (no reply)' means that hop didn't answer — common, since many routers rate-limit or drop ICMP; it isn't necessarily a fault.
- If the trace reaches the destination, the path is healthy end-to-end.
- If the last several hops are silent and it never reaches the target, traffic may be filtered near the destination or the host is down.
Frequently asked questions
Why run traceroute from your server instead of my computer?
Browsers and phones can't send raw ICMP packets, so an in-page traceroute isn't possible. Running it from our nodes also shows the path from the public internet to your target — the perspective that matters for diagnosing reachability.
What does '* (no reply)' mean for a hop?
That router didn't return an ICMP Time Exceeded message — usually because it rate-limits or drops ICMP. The path can still be fine; the probe just got no answer from that one hop.
Does it support IPv6 traceroute?
Yes. Enter an IPv6 address (or a host with an AAAA record) and the trace runs over IPv6 using ICMPv6.
Why doesn't the trace reach my host?
Either the final hops filter ICMP, or the host is unreachable. Compare with a TCP ping to the service port — if the port answers but traceroute doesn't complete, ICMP is simply being filtered.
