Altdns is a Python CLI tool for DNS reconnaissance that generates permutations, alterations, and mutations of known subdomains using a wordlist. It can optionally resolve the generated candidate subdomains multi-threaded to find valid DNS records.
Use cases
- discover subdomains that follow naming patterns like dev or staging
- generate permuted subdomain lists for DNS bruteforcing tools
- resolve mutated subdomain candidates to find live hosts
- expand a small known subdomain list into a larger attack surface
- enumerate hidden environments in a domain during recon
When to choose
- you already have a seed list of subdomains and want pattern-based expansion
- you want a fast, scriptable CLI that plugs into existing recon pipelines
- you need multi-threaded DNS resolution of generated candidates
When to avoid
- you have no initial subdomain data, as it works best with 200+ known subdomains
- you need a full-featured modern subdomain enumeration suite rather than a single-purpose permutation tool
- you require active maintenance or Python 3-first support guarantees
