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