    Use Cases & Benefits

    • Provides a fast, modern traceroute tool with real-time terminal UI, per-hop statistics, ASN/geo lookup, ECMP detection, and MPLS label parsing.
    • Delivers advanced network diagnostics beyond traditional traceroute, including MTU discovery, NAT detection, route flap alerts, and multi-target tracing with rich visualizations.
    • Use for continuous path monitoring and latency analysis with detailed hop statistics in a terminal interface.
    • Use for detecting network issues like MTU blackholes, NAT rewriting, and route flapping in complex network environments.
    • Use for headless network monitoring with Prometheus metrics export and automated trace diffing for CI/CD or production observability.
