So we can see by just giving simple command we have name servers, mail servers, host address and much more things. The results vary from website to website and scope enhances when there are sub domains in the target website.
We can also use DNSENUM to scrap the sub domains of a website from Google. For doing this we need to type below command :
./dnsenum.pl -p 1 -s 1 example.com
Scrapping will not work on those websites which do not have sub domains and for those websites which has restricted wild card scrapping.
That's all for today frens. Hope this helps, you can practice multiple combinations and sub commands mentioned below to extract juicy information regarding DNS's for any domain.
