shuffledns -d example.com -w subdomains.txt -r resolvers.txt

# Output resolved subdomains
shuffledns -d example.com -w subdomains.txt -r resolvers.txt -o resolved.txt

When to Use

Resolving subdomains from a wordlist

Filtering out wildcard DNS entries

Validating bulk subdomain lists

Mass DNS resolution with bruteforce

Notes & Tips

Designed to handle wildcard DNS efficiently

Use a curated resolvers list for best results

Part of ProjectDiscovery toolchain — pairs with subfinder, dnsx

Fast enough for million+ wordlist bruteforcing

Common Errors & Solutions

Wildcard detection false positives

Provide more resolvers and increase -wildcard-threshold to 5+

Slow resolution with large wordlists

Increase thread count with -t and use faster resolvers
