most routers respond to ICMP; TCP/443 sometimes reaches hosts that suppress it
city-level accuracy at best; some hops (anycast, ISP-registered routers) have no reliable location at all
Runs a real traceroute from this server and shows who actually owns each hop — not a map, since IP geolocation doesn't reliably indicate a physical route. Network ownership (ASN) does.
An optional map view below plots each hop's coarse, city-level approximate location for illustration only — it is a secondary, best-effort signal and is never a substitute for the ASN data, which remains authoritative.
