Network Path Analyzer
Deep analysis of network routing with hop-by-hop latency measurement, ASN identification, and geographic path visualization.
About Traceroute
Visual traceroute tool that shows the complete network path between our global probes and your target. Identify routing issues and network hops.
Key Features
Multi-region traceroute
Hop-by-hop latency
RTT visualization
Packet loss detection
Destination reach status
Network path analysis goes beyond basic traceroute to provide detailed performance insights at each hop. For IT teams and network engineers, understanding WHERE latency occurs—which autonomous systems (ASNs), which geographic regions, which peering points—is essential for optimization and troubleshooting.
Our path analyzer measures hop-by-hop latency from 6+ global locations, identifying routing inefficiencies, congested links, and suboptimal paths. Unlike simple route tracing, this tool focuses on performance analysis: which hops add latency, where packet loss occurs, and how paths differ by geography.
For complete network diagnostics, combine path analysis with port checking to verify connectivity and latency testing to measure end-to-end performance once the path is understood.
**Methodology:** Traceroute with ASN lookup from 6 regions, measuring per-hop latency with 3 probes per hop for accuracy.
Common Errors & How to Fix Them
3 relevant issuesOne or more hops show significantly higher latency than others. Could indicate congestion, distance, or router performance issues.
1) Check if high latency persists to destination or recovers. 2) If only that hop is slow: router may deprioritize ICMP (not a real problem). 3) If latency stays high: bottleneck identified. 4) For geographic hops (100ms+ jumps): expected for intercontinental links. 5) Persistent issues: contact ISP with evidence.
Traceroute shows hops up to a point, then only asterisks. Traffic is being blocked or dropped at that hop.
1) Identify the last responding hop—that's where blocking occurs. 2) Check if it's your ISP, a transit provider, or destination's network. 3) Try TCP traceroute: traceroute -T -p 443 target.com. 4) Contact the network operator if it's a provider issue. 5) If destination's network, firewall is blocking.
Traceroute shows the same IP addresses repeating. Packets are going in circles due to misconfigured routing tables.
1) Note the IPs involved in the loop. 2) If it's within your network: check router configurations for circular routes. 3) If it's external: report to ISP with traceroute output. 4) Try alternative route: use VPN to bypass problematic path. Routing loops are usually resolved within hours by network operators.
Frequently Asked Questions
3 relevant questionsEach line shows a hop number, router IP/hostname, and three response times (in milliseconds). Asterisks (*) mean the router didn't respond—this doesn't always indicate a problem, as some routers are configured not to respond to traceroute. Look for sudden latency increases between hops to identify bottlenecks.
High latency at a hop can indicate: congested router, undersized link, geographic distance (intercontinental hops add 50-150ms), or the router deprioritizing ICMP responses. If latency increases and stays high for subsequent hops, the bottleneck is real. If only one hop shows high latency but the next is normal, it's likely just slow ICMP response.
Network paths vary by geography. A traceroute from the US to a server in Germany takes a different route than from Asia. Multi-region traceroute reveals routing inefficiencies, identifies regional network issues, and helps diagnose "works from here but not there" problems. It's essential for global services.
