# Enumeração de DNS

A enumeração de DNS identifica domínios, subdomínios, registros, servidores de nomes, zonas expostas e indícios de infraestrutura antes de uma varredura mais profunda. Use primeiro fontes passivas e, em seguida, valide os achados com consultas DNS ativas e força bruta controlada quando o escopo do teste permitir.

## Fluxo de Trabalho de Enumeração de DNS

1. Colete dados passivos de DNS de fontes públicas e conjuntos de dados de transparência de certificados.
2. Consulte registros comuns como A, AAAA, CNAME, MX, TXT, NS, SOA e SRV.
3. Verifique a exposição a transferência de zona com servidores de nomes autorizados.
4. Faça força bruta de subdomínios somente quando as regras de engajamento permitirem descoberta ativa.
5. Resolva os hosts descobertos e encaminhe os alvos confirmados para a varredura de portas e a criação de perfis web.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://hacking-notes.jord4n.pro/pt-br/hacking-tools/enumeration/dns-enumeration.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.
