DESCRIPTION

       dsnrecon is a simple python script that enables to gather DNS-oriented information on a given target.

OPTIONS

       -h, --help
              show help message and exit

       -d DOMAIN, --domain DOMAIN
              Target domain.

       -n NS_SERVER, --name_server NS_SERVER
              Domain  server  to use. If none is given, the SOA of the target will be used. Multiple servers can
              be specified using a comma separated list.

       -r RANGE, --range RANGE
              IP range for reverse lookup brute force in formats (first-last) or in (range/bitmask).

       -D DICTIONARY, --dictionary DICTIONARY
              Dictionary file of subdomain and hostnames to use for brute  force.  Filter  out  of  brute  force
              domain lookup, records that resolve to the wildcard defined IP address when saving records.

       -f     Filter  out  of brute force domain lookup, records that resolve to the wildcard defined IP address
              when saving records.

       -a     Perform AXFR with standard enumeration.

       -b     Perform Bing enumeration with standard enumeration.

       -s     Perform a reverse lookup of IPv4 ranges in the SPF record with standard enumeration.

       -y     Perform Yandex enumeration with standard enumeration.

       -k     Perform crt.sh enumeration with standard enumeration.

       -w     Perform deep whois record analysis and reverse lookup of IP ranges found through Whois when  doing
              a standard enumeration.

       -z     Performs a DNSSEC zone walk with standard enumeration.

       --threads THREADS
              Number  of  threads  to  use  in  reverse  lookups,  forward  lookups,  brute force and SRV record
              enumeration.

       --lifetime LIFETIME
              Time to wait for a server to respond to a query. default is 3.

       --tcp  Use TCP protocol to make queries.

       --db DB
              SQLite 3 file to save found records.

       -x XML, --xml XML
              XML file to save found records.

       -c CSV, --csv CSV
              Comma separated value file.

       -j JSON, --json JSON
              JSON file.

       --iw   Continue brute forcing a domain even if wildcard records are discovered.

       --disable_check_recursion
              Disables check for recursion on name servers

       --disable_check_bindversion
              Disables check for BIND version on name servers

       -v     Enable verbose

       -V     Show version

       -t TYPE, --type TYPE
              Type of enumeration to perform. There are several possible types:

              • std: SOA, NS, A, AAAA, MX and SRV.

              • rvl: Reverse lookup of a given CIDR or IP range.

              • brt: Brute force domains and hosts using a given dictionary.

              • srv: SRV records.

              • axfr: Test all NS servers for a zone transfer.

              • bing: Perform Bing search for subdomains and hosts.

              • yand: Perform Yandex search for subdomains and hosts.

              • crt: Perform crt.sh search for subdomains and hosts.

              • snoop: Perform cache snooping against all NS servers for a given domain, testing all  with  file
              containing the domains, file given with -D option.

              • tld: Remove the TLD of given domain and test against all TLDs registered in IANA.

              • zonewalk: Perform a DNSSEC zone walk using NSEC records.

EXAMPLES

       attempts a zone transfer (AXFR) on the zonetransfer.me domain
              dnsrecon -t axfr -d zonetransfer.me

                                                                                                     DNSRECON(1)
