## What it is
dnsx is a fast, multi-purpose DNS toolkit from ProjectDiscovery for running DNS queries (A, AAAA, CNAME, PTR, NS, MX, TXT, SRV, SOA) with user-supplied resolvers. It supports DNS resolution, brute-forcing, and automatic wildcard filtering via the retryabledns library.

## Use cases
- resolve a list of subdomains to IP addresses
- brute-force subdomains of a domain with a wordlist
- query DNS records like MX, TXT, or CNAME for a domain
- filter out wildcard DNS responses during enumeration
- use custom resolvers including DoH and DoT
- pipe domains through stdin for DNS resolution in a recon pipeline

## When to choose
- you need fast, scriptable DNS resolution or record lookups in a security/recon workflow
- you want wildcard filtering and custom resolver support (TCP/UDP/DoH/DoT)
- you want a lightweight CLI that fits into pipelines with stdin/stdout

## When to avoid
- you need a full DNS server or zone management tool
- you want a GUI-based DNS lookup utility
- you need historical DNS data, which requires external data sources
