# Lista de permissões de IP
Aprenda a criar ou editar uma lista de permissões de IP para os proxies de datacenter da Oxylabs.
Autentique seus IPs criando a lista de permissões de IP no [**painel**](https://dashboard.oxylabs.io/en/).
1. Faça login na sua conta e abra sua instância de proxy Datacenter.
2. Abra **Configurador** aba, clique em **Autenticação** e procure por **lista de permissões**.
3. Adicione até 10 IPs no formato IPv4 (`xx.xx.xx.xx`).
Com a lista de permissões de IP, você pode fornecer `país` parâmetro em `nome de usuário` campo.\
Ao executar o comando cURL, não se esqueça de adicionar uma "`:`" no final de `nome de usuário` string para impedir que o cURL solicite uma senha.
```bash
curl -x dc.oxylabs.io:8000 -U 'country-US:' https://ip.oxylabs.io/location
```
Ao adicionar um endereço IP à lista de permissões, certifique-se de que ele pertença exclusivamente a você e evite conectar-se por meio de serviços de Proxy ou VPN.
Se você estiver usando serviços como Amazon Web Services (AWS), recomendamos fortemente usar autenticação por nome de usuário e senha em vez de depender apenas da lista de permissões de IP.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://developers.oxylabs.io/products/pt-br/proxies/datacenter-proxies/whitelisting.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
