SYNOPSISdnsrecon <options>
OPTION-h, --help
Show help message and exit
-d, --domain <domain>
Domain to Target for enumeration.
-r, --range <range>
IP Range for reverse look-up brute force in formats (first-last)
or in (range/bitmask).
-n, --name_server <name>
Domain server to use, if none is given the SOA of the
target will be used
-D, --dictionary <file> (use absolute path)
Dictionary file of sub-domain and hostnames to use for
brute force.
-f Filter out of Brute Force Domain lookup records that resolve
to the wildcard defined IP Address when saving records.
-t, --type <types>
Specify the type of enumeration to perform:
std To Enumerate general record types, enumerates.
SOA, NS, A, AAAA, MX and SRV if AXRF on the
NS Servers fail.
rvl To Reverse Look Up a given CIDR IP range.
brt To Brute force Domains and Hosts using a given
dictionary.
srv To Enumerate common SRV Records for a given
domain.
axfr Test all NS Servers in a domain for misconfigured
zone transfers.
goo Perform Google search for sub-domains and hosts.
snoop To Perform a Cache Snooping against all NS
servers for a given domain, testing all with
file containing the domains, file given with -D
option.
tld Will remove the TLD of given domain and test against
all TLD's registered in IANA
zonewalk Will perform a DNSSEC Zone Walk using NSEC Records.
-a Perform AXFR with the standard enumeration.
-s Perform Reverse Look-up of ipv4 ranges in the
SPF Record of the targeted domain with the
standard enumeration.
-g Perform Google enumeration with the standard
enumeration.
-w Do deep whois record analysis and
reverse look-up of IP ranges found thru whois
when doing standard query.
-z Performs a DNSSEC Zone Walk with the standard
enumeration.
--threads <number>
Number of threads to use in Range Reverse Look-up,
Forward Look-up Brute force
and SRV Record Enumeration
--lifetime <number>
Time to wait for a server to response to a query.
--db <file> (use absolute path) SQLite 3 file to save
found records.
--xml <file> (use absolute path) XML File to save found
records.
-c, --csv <file> (use absolute path) Comma separated value
file.
-v Show attempts in the bruteforce modes.
DESCRIPTION
I wrote this tool back in late 2006 and it has been my favorite tool
for enumeration thru DNS, in great part because I wrote it and it gives
the output in a way that I can manipulate it in my own style. One of
the features that I used the most and gave me excellent results is the
SRV record enumeration.
The script will perform the following:
Standard Record Enumeration for a given domain (A, NS, SOA and MX).
Top Leven Domain Expansion for a given domain. Zone Transfer against
all NS records of a given domain. Reverse Lookup against a given IP
Range given a start and end IP.
SRV Record enumeration, enumerating:
_gc._tcp.
_kerberos._tcp.
_kerberos._udp.
_ldap._tcp.
_test._tcp.
_sips._tcp.
_sip._udp.
_sip._tcp.
_aix._tcp.
_aix._tcp.
_finger._tcp.
_ftp._tcp.
_http._tcp.
_nntp._tcp.
_telnet._tcp.
_whois._tcp.
_h323cs._tcp.
_h323cs._udp.
_h323be._tcp.
_h323be._udp.
_h323ls._tcp.
_h323ls._udp.
Brute force hostnames and subdomains of a given target domain using a
wordlist.
