+# 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}}`
