traceroute - Trace the route to HOST (IPv4)

**Description:** traceroute tracks the route packets take through an IP network on their way to a given host.

**Usage:**

```
traceroute [-C VCE] [-FIldnrv] [-f 1ST_TTL] [-m MAXTTL] [-p PORT]
        [-q PROBES] [-s SRC_IP] [-t TOS] [-w WAIT_SEC] [-g GATEWAY] [-i IFACE]
        [-z PAUSE_MSEC] HOST [BYTES]
```

**Options:**

| Option | Description |
| --- | --- |
| -C | Send a traceroute through a specific VCE. |
| -F | Set the don't fragment bit. |
| -I | Use ICMP Echo instead of UDP datagrams. |
| -l | Display the TTL value of the returned packet. |
| -d | Set SO_DEBUG options to socket. |
| -n | Print numeric addresses. |
| -r | Bypass routing tables, send directly to HOST. |
| -v | Verbose. |
| -f | TTL to start with (default 1). |
| -m | Max time-to-live (max number of hops). |
| -p | Base UDP port number used in probes (default 33434). |
| -q | Number of probes per TTL (default 3). |
| -s | IP address to use as the source address. |
| -t | Type-of-service in probe packets (default 0). |
| -w | Time in seconds to wait for a response (default 3). |
