# DNS Ads Filter

<figure><img src="/files/iNzFHgFPWj81Qn88Zk80" alt=""><figcaption><p>DNS Filtering</p></figcaption></figure>

The DNS Filtering primarily intercepts ads, tracking codes, and web page-imbedded malware in DNS access requests.&#x20;

The top row indicates the total number of DNS requests analyzed during AtomOS runtime, the number of intercepted DNS requests, and the interception ratio.&#x20;

The bottom row indicates the numbers of each blocking item (Blocked ads, trackers and malicious). By switching on (blue) indicates that the blocking is enabled. While switching off (gray) indicates the blocking is disabled.

It is recommended to enable all three at the same time.

*Note: Please click the "**View**" to read the instructions on how to disable DoH. Otherwise, the DNS Ads Filter may fail to block ads effectively.*

## Querying This Documentation
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, and the optional `goal` query parameter:

```
GET https://deeper-network-inc.gitbook.io/deeper-connect-knowledge-base/atom-os-functions/ads-block/dns-ads-filter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
