Quick Tip #2 – dnsmap

by JeffSoh on April 24, 2020

dnsmap – command line utility to map out DNS records, bypassing the prohibition on zone transfers…

dnsmap is a great little tool to enumerate as many sub-domains on a target as possible. It’s very easy to use and add to a script. Here’s the parameters:

[root@legolas /]# dnsmap
dnsmap 0.30 – DNS Network Mapper by pagvac (gnucitizen.org)
usage: dnsmap [options]
options:
-w
-r
-c
-d
-i (useful if you’re obtaining false positives)
e.g.:
dnsmap target-domain.foo
dnsmap target-domain.foo -w yourwordlist.txt -r /tmp/domainbf_results.txt
dnsmap target-fomain.foo -r /tmp/ -d 3000
dnsmap target-fomain.foo -r ./domainbf_results.txt

Now a quick run for the wired.com domain… I stopped it before it completed as this was just an example for educational purposes only

[root@legolas /]# dnsmap wired.com
