We will learn how to gather DNS information about all the subdomains of a web application or website using DNSMAP network mapper tool. DNSMAP is basically an sub domain mapping tool which gives all the subdomains, their corresponding IPv4 IP address and IPv6 IP address as output.
Unlike other tools, where we use brute force technology to gather all sub domains we dont have a feature to abort the brute forcing if domain uses wildcards technically you can say it producing false positives while enumerating sub domain data. So friends lets first discuss the key features of DNSMAP and what all we can gather using it.
Step 1 : just type dnsmap on the kali linux terminal.
Step 2 : Then Enter you Target Website that you want to do Subdomains Enumaration.
Here I have used "techtrick.in" for demo purpose.
dnsmap www.techtrick.in -r /root/Desktop/Result.txt
