tracepath
TLDR
Trace path to a host with MTU discovery
SYNOPSIS
tracepath [options] host
DESCRIPTION
tracepath traces the path to a network host, discovering the MTU (Maximum Transmission Unit) along the path. Unlike traceroute, it does not require superuser privileges and can detect path MTU.
The output shows each hop with its RTT and MTU information.

Print both hostnames and numerical IP addresses-m _max_hops_
Set maximum number of hops (TTL)-l _length_

CAVEATS
