tracepath

Trace the path to a network host discovering MTU along this path.

• 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}
