# recon\_16 (bind version)

View the exercise here: [PentesterLab: Recon 16](https://pentesterlab.com/exercises/recon_16/course)

### **OBJECTIVE**

For this challenge, your goal is to get the version of bind used by **z.hackycorp.com**.

### **BIND**

[Bind](https://www.isc.org/bind/) is one of the most common DNS servers used. If you know how to ask, it will reveal its version.

### **SOLUTION**

{% hint style="success" %}

```bash
dig @z.hackycorp.com version.bind CHAOS TXT
```

* **`dig`**: The tool used for querying DNS.
* **`@z.hackycorp.com`**: Specifies the DNS server (`z.hackycorp.com`) to query.
* **`version.bind`**: This asks for the version of the DNS server.
* **`CHAOS`**: The DNS class used for special queries like retrieving server information (in this case, the version).
* **`TXT`**: Requests the response as a text record (where the version info is stored).
