SYNOPSIS
nexttrace [*options*] *host*
DESCRIPTION
nexttrace (NTrace) is an enhanced traceroute implementing multiple protocols with ASN lookups, geolocation, and polished terminal output. Developed as nxtrace/NTrace-core; the user-facing binary is typically nexttrace. Available via package managers and release builds for many architectures.
PARAMETERS
*host*
Target hostname or IP.Common flags (names vary by version): protocol selection (ICMP/TCP/UDP), max hops, parallel probes, language, and --json. Always prefer nexttrace --help.
INSTALL
brew install nexttrace
nix profile install nixpkgs#nexttrace
CAVEATS
Raw sockets/privileges may be required for some probe types. Geolocation databases can be wrong. Respect remote networks—do not abuse high-rate probing.
