tracepath

Trace the path to a network host discovering MTU along this path. More information: https://manned.org/tracepath.

• A preferred way to trace the path to a host:

tracepath -p 33434 host

• Specify the initial destination port, useful with non-standard firewall settings:

tracepath -p destination_port host

• Print both hostnames and numerical IP addresses:

tracepath -b host

• Specify a maximum TTL (number of hops):

tracepath -m max_hops host

• Specify the initial packet length (defaults to 65535 for IPv4 and 128000 for IPv6):

tracepath -l packet_length host

• Use only IPv6 addresses:

tracepath -6 host
