## What it is
Puredns is a fast command-line domain resolver and subdomain bruteforcing tool written in Go. It uses massdns for bulk DNS lookups and applies a wildcard detection algorithm plus trusted-resolver validation to filter out wildcard subdomains and DNS-poisoned entries.

## Use cases
- bruteforce subdomains of a domain using a wordlist
- resolve a large list of domains quickly with public resolvers
- filter wildcard subdomains from DNS enumeration results
- clean up massdns output polluted by false positives
- detect DNS poisoning in resolution results
- integrate DNS resolution into bug bounty recon pipelines via stdin

## When to choose
- you need accurate subdomain enumeration for bug bounty or recon
- you want fast bulk DNS resolution with wildcard filtering
- you need pipeline-friendly stdin/stdout DNS tooling

## When to avoid
- you need a general-purpose DNS server or recursive resolver
- you only need a handful of DNS lookups and a simple dig-style tool suffices
- you require a GUI or managed service rather than a CLI
