traceroute6 - Trace the route to HOST (IPv6)

**Description:** traceroute6 tracks the route packets take through an IPv6 network on their way to a given host.

**Note:** The traceroute command supports both IPv4 and IPv6, so traceroute6 is equivalent to traceroute, however some parameters used in IPv4 may not be valid for IPv6.

**Usage:**

```
traceroute6 [-C VCE] [-dnrv] [-m MAXTTL] [-p PORT] [-q PROBES]
        [-s SRC_IP] [-t TOS] [-w WAIT_SEC] [-i IFACE]
        HOST [BYTES]
```

**Options:**

| Option | Description |
| --- | --- |
| -C | Send a traceroute through a specific VCE. |
| -d | Set SO_DEBUG options to socket. |
| -n | Print numeric addresses. |
| -r | Bypass routing tables, send directly to HOST. |
| -v | Verbose. |
| -m | Max time-to-live (max number of hops). |
| -p | Base UDP port number used in probes (default is 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). |
