Routing visibilityWhy enriched traceroute helps
Traceroute shows the path packets take from the Zerolink server toward a destination. Each hop is a router or gateway along the route. When a website or server feels slow or unreachable, traceroute helps identify where the path changes or stops responding.
This tool enriches each hop with reverse DNS hostnames, IP registry information and registered location data using RDAP and public IP sources. That makes it easier to see whether delay appears inside an ISP network, at a transit provider or near the destination itself.
Results originate from the Zerolink server, not your own connection. Start with DNS lookup if naming is uncertain, then compare with ping for reachability, the internet speed test for connection performance, and the Network Diagnostics Suite for broader checks.
Traceroute lookup questions
What is the difference between this page and the IP ping tool?
The IP ping tool runs a quick reachability check with optional raw traceroute output. This page focuses on traceroute and adds reverse DNS hostnames, IP registry details and registered location for every hop in a structured table.
Where does the IP registry name come from?
Registry information is looked up from RDAP registration data with a fallback to public IP geolocation providers when RDAP does not return an organisation name.
What does the location column show?
Location shows the registered or geolocated place associated with the hop IP, usually city, region and country when available from public IP data sources.
Why do some hops show a timeout?
Many routers are configured not to reply to traceroute probes. A timeout on an intermediate hop does not always mean the path is broken.
Why does the hostname column show a dash?
A dash means no PTR reverse DNS record was available for that hop, or the router did not publish a resolvable hostname in the traceroute response.
Is the test run from my computer?
No. Traceroute runs from the Zerolink web server. Routing and latency can differ from what you see on your own ISP connection.
Can I traceroute private IP addresses?
No. Only public destinations are accepted. Private, local and reserved addresses are blocked for safety.
How many hops are tested?
Up to 15 hops are requested per trace. Long paths may stop earlier if the destination responds sooner.
Should I use traceroute or a speed test first?
Use the internet speed test when you want to measure latency, download and upload on your own connection. Use traceroute when DNS and ping look fine but you need to see which network hops sit between the Zerolink server and the destination.
Should I test a domain or an IP address?
Both work. Testing a domain also shows current DNS A and AAAA records above the hop table, which is useful when a hostname recently changed.
