# Enumerate Hostnames via Permutation DNS Brute Force
## Description
Enumerate hostnames by checking for permutations of known hostnames. This module finds different environments, regions, and associated software. It has an effective built-in wordlist but you can also use a custom wordlist tailored to your organization’s naming conventions.
## Features
* Discovers **different environments, regions, and associated software** based on the input hostnames.
* **Built-in wordlists** with the option to **use custom ones** tailored to your target.
* A **daily validated list of resolvers** to ensure accuracy.
* Result **verification using manually curated trusted resolvers**.
* A **wildcard filter** takes care of false positives.
## Inputs
### Required
* **hostnames**: a list of hostnames
```
dashboard.example.com
shop.example.com
payments.example.com
```
## Outputs
* **subdomains**: a list of found subdomains
```
dev-dashboard.example.com
shop.us-east-1.example.com
payments-log.example.com
```
* **subdomain-details**: JSONLines records of subdomain discovery details.
