ttl è un mtr con qualche funzione in più, tra cui enrichment dei dati ASN e DNS:
Key features of ttl include:
• Multi-flow probing – Enumerates all load-balanced paths (no more seeing just one path through ECMP).
• Path MTU discovery – Pinpoints exactly where fragmentation kills your jumbo frames.
• NAT detection – Reveals when a middlebox is quietly rewriting your source ports.
• Route flap alerts – Catches BGP instability as it happens by detecting path changes in real time.
• PeeringDB integration – Identifies which Internet Exchange (IX) you're crossing in your route.
• MPLS label visibility – Exposes provider LSP paths by decoding MPLS labels from ICMP responses.
• Smart loss detection – Distinguishes real packet loss from routers simply rate-limiting ICMP replies.
• Modern TUI – Features live stats, jitter calculation, ASN/GeoIP enrichment, and a sleek terminal UI (no 1990s look-and-feel).
• Scriptable output – JSON and CSV export for automating analysis or proving that yes, the problem is their network.
