## Impact

A default VPC is a VPC that is created for your AWS account when you create an AWS account. It includes a default security group and a default network access control list (NACL). Default VPCs have some limitations that might not be suitable for all use cases. Therefore, if you have specific requirements for your VPC, such as custom IP address ranges, support for PrivateLink or Transit Gateway, or the ability to delete the VPC, it might be more appropriate to create a custom VPC instead of using the default VPC.

## How to Fix

## It is recommended for this resource to not be configured \[source,go]

## resource "aws\_default\_vpc" "default" { tags = { Name = "Default VPC" } }

## 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://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/networking/appsec-aws-148.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.
