dnsx

A fast and multi-purpose DNS toolkit to run multiple DNS queries. Note: input to dnsx needs to be passed through stdin (pipe |) in some cases. See also: dig, dog, dnstracer. More information: https://github.com/projectdiscovery/dnsx.

• Query the A record of a (sub)domain and show [re]sponse received:

echo {{example.com}} | dnsx -a -re

• Query all the DNS records (A, AAAA, CNAME, NS, TXT, SRV, PTR, MX, SOA, AXFR, CAA):

dnsx -recon -re <<< {{example.com}}

• Query a specific type of DNS record:

echo {{example.com}} | dnsx -re -{{a|aaaa|cname|ns|txt|srv|ptr|mx|soa|any|axfr|caa}}

• Output [r]esponse [o]nly (do not show the queried domain or subdomain):

echo {{example.com}} | dnsx -ro

• Display raw response of a query, specifying [r]esolvers to use and retry attempts for failures:

echo {{example.com}} | dnsx -{{debug|raw}} -resolver {{1.1.1.1,8.8.8.8,...}} -retry {{number}}

• Brute force DNS records using a placeholder:

dnsx -domain {{FUZZ.example.com}} -wordlist {{path/to/wordlist.txt}} -re

• Brute force DNS records from a list of [d]omains and wordlists, appending [o]utput to a file with [n]o [c]olor codes:

dnsx -domain {{path/to/domain.txt}} -wordlist {{path/to/wordlist.txt}} -re -output {{path/to/output.txt}} -no-color

• Extract CNAME records for the given list of subdomains, with [r]ate [l]imiting DNS queries per second:

subfinder -silent -d {{example.com}} | dnsx -cname -re -rl {{number}}
