Installation Instructions
From Source
dnsprobe requires go1.13+ to install successfully. Run the following command to get the repo -
GO111MODULE=on go get -v github.com/projectdiscovery/dnsprobe

For example, to query a list of domains for CNAME record and output the results to your host file system:
> cat domains.txt | docker run -i projectdiscovery/dnsprobe -r CNAME > bugcrowd.txt
Querying host for A record
To query a list of domains, you can pass the list via stdin (it also accepts full URLS, in this case the domain is extracted automatically).
> cat domains.txt | dnsprobe
root@test:~# cat bc.txt | dnsprobe
