tldfinder is a tls data gathering and analysis toolkit.A streamlined tool for discovering TLDs, associated subdomains, and related domain names.Usage: ./tldfinder [flags]Flags:INPUT: -d, -domain string[] domain or list of domains for discovery (file or comma separated)SOURCE: -s, -sources string[] specific sources to use for discovery (-s censys,dnsrepo). Use -ls to display all available sources. -es, -exclude-sources string[] sources to exclude from enumeration (-es censys,dnsrepo) -dm, -discovery-mode value discovery mode (dns,tld,domain) (default dns) -all use all sources for enumeration (slow)FILTER: -m, -match string[] domain or list of domain to match (file or comma separated) -f, -filter string[] domain or list of domain to filter (file or comma separated)RATE-LIMIT: -rl, -rate-limit int maximum number of http requests to send per second (global) -rls, -rate-limits value maximum number of http requests to send per second four providers in key=value format (-rls hackertarget=10/m) (default ["waybackarchive=15/m", "whoisxmlapi=50/s", "whoisxmlapi=30/s"]) -t int number of concurrent goroutines for resolving (-active only) (default 10)UPDATE: -up, -update update tldfinder to latest version -duc, -disable-update-check disable automatic tldfinder update checkOUTPUT: -o, -output string file to write output to -oJ, -json write output in JSONL(ines) format -oD, -output-dir string directory to write output (-dL only) -cs, -collect-sources include all sources in the output (-json only) -oI, -ip include host IP in output (-active only)CONFIGURATION: -config string flag config file (default "/Users/user/Library/Application Support/tldfinder/config.yaml") -pc, -provider-config string provider config file (default "/Users/user/Library/Application Support/tldfinder/provider-config.yaml") -r string[] comma separated list of resolvers to use -rL, -rlist string file containing list of resolvers to use -nW, -active display active domains only -proxy string http proxy to use with tldfinder -ei, -exclude-ip exclude IPs from the list of domainsDEBUG: -silent show only domains in output -version show version of tldfinder -v show verbose output -nc, -no-color disable color in output -ls, -list-sources list all available sources -stats report source statisticsOPTIMIZATION: -timeout int seconds to wait before timing out (default 30) -max-time int minutes to wait for enumeration results (default 10)
tldfinder requires domain or tld as input for any discovery mode.
io # TLD inputgoogle.io # Domain input (tld will be auto extracted from domain name)
Input can be provided using -domain / -d
flag, and multiple values can be provided using comma-separated input.
Example run:
