What does a traceroute show?

A traceroute shows the path (each router/hop) that data packets take from our server in Düsseldorf to the destination – including the response time of each hop. This helps reveal routing paths and possible bottlenecks.

Why do asterisks (*) appear instead of an IP?

Some routers do not reply to traceroute packets for security reasons, or drop them silently. Such hops appear as “* (no reply)” – the route still continues to the next responding hop.

Can I use hostnames, IPv4 and IPv6?

Yes. You can enter a domain name, an IPv4 or an IPv6 address. Hostnames are resolved before the traceroute; internal/private addresses are not allowed for security reasons.

Does it measure my own path to the target?

No. The traceroute starts from our server in Germany, not from your connection. It shows the route from the German internet to the destination.

Traceroute – Trace the Network Route to a Website or IP

Enter a domain, IPv4 or IPv6 address to trace the network route. The traceroute is started from our server in Düsseldorf, Germany.

What is a traceroute?

A traceroute traces the path your data packets take through the internet to a destination. Each intermediate stop (a router, called a “hop”) is listed with its IP address, the associated network (ASN) and the measured response time. This shows which networks the traffic passes through and where delays occur.

For every hop we provide direct links to our IP Lookup (location, provider, reverse DNS) and to the ASN lookup (autonomous system). Hops that do not respond appear as “*” – this is normal, since many routers do not answer traceroute packets for security reasons. The traceroute runs from our server in Germany and therefore shows the route from the perspective of the German internet.
