# NetPractice

Okay - let's put the code aside for a second and get down to something mystical: networks.

* How do two machines communicate with each other?
* What is the Internet anyway?
* Do you even know what an IP address is?

All these network-related questions can be answered to perfection thanks to NetPractice, a project from 42.

### NetPractice in short

What you'll have to do:

* Download a file from your intra site

Once that's done, you're going to have some fun with a few problem-solving games:

* You'll need to configure small networks. To do this, you'll need to understand how addressing works with the TCP/IP protocol. (You'll have 10 levels)

Here's an example:

The aim is to link all the machines in each level.

It sounds easy enough, but if you're not an expert, it can be hard to find the information you need.&#x20;

So click on the next page and let's take a look at how it all works :)

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://42-cursus.gitbook.io/guide/4-rank-04/netpractice.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
