Hop-by-hop path with per-hop latency and ASN owner.
Traceroute discovers the layer-3 path packets take from our probe to a destination, revealing every intermediate hop (router), the round-trip latency to each, and the ASN that owns each hop so you can see where traffic enters a given network.
Enter a hostname or IP address and run the tool. The probe increments the time-to-live value to force each successive router to respond, mapping the full path to the destination.
Input: Hostname or IP — e.g. 198.51.100.24.
Each row is one hop, numbered from 1. The columns show the hop address, resolved hostname, ASN owner, and the latency of each probe attempt. A row of asterisks (* * *) means that hop did not respond within the timeout — common for routers that rate-limit ICMP. A sudden latency jump often pinpoints the link or network where congestion or a routing problem begins.
→ Find which hop or ASN a latency spike is introduced at.
→ Confirm traffic is taking the expected transit path to a partner.
→ Diagnose why one region reaches a service slower than another.
→ Identify the ISP or carrier responsible for a black-hole segment.
Those routers received the probe but chose not to reply with an ICMP time-exceeded message, usually because they rate-limit or block ICMP for security. The path continues beyond them — asterisks do not mean the route is broken, only that the hop is silent.
A latency jump at hop N usually indicates the delay is introduced on the link between hop N-1 and hop N, or by hop N itself. However, asymmetric return paths can make a hop look slow when the real delay is elsewhere, so confirm with multiple runs.
It shows the path from our probe network to the target. Your users’ traffic enters the internet from their own ISP, so their path can differ. Run it from multiple vantage points or compare with the BGP Route View tool to understand variation.
