Question

DNS lookup for a list of domains

Hi all,

I have a list of domains (about 100 or so) in a text file called domains.txt, I want to find out the A records of all of those domains but I don’t want to do it manually for each single domain.

Is there a command that I could use to do this automatically for all domains?

Thanks!

Hello,

Yes, you could use this command to do a quick DNS lookup for all of the domains in the domains.txt file:

cat domains.txt |xargs -I % echo "echo % ; dig +short %" | sh

Hope that this helps! Regards, Bobby
