Focused crawls are collections of frequently-updated webcrawl data from narrow (as opposed to broad or wide) web crawls, often focused on a single domain or subdomain.
shuffleDNS is a wrapper around massdns written in go that allows you to enumerate valid subdomains using active bruteforce as well as resolve subdomains with wildcard handling and easy input-output support.
Bass grabs you those "extra resolvers" you are missing out on when performing Active DNS enumeration. Add anywhere from 100-6k resolvers to your "resolver.txt"
puredns is a subdomain bruteforcing tool that improves massdns to accurately handle wildcard subdomains and DNS poisoning. Easy to use and to integrate into workflows, it ensures the results obtained by public resolvers are clean.
