What are some good free tools for domain recon for a beginner?

As the title says, I’ve kind of been thrown into the deepend without any experience in this field whatsoever. I have a mentor however he’s incredibly busy and I’ve just been told “do this”.


I’m really passionate about cyber and it’s a field I’d love to get into so if anyone has some tips and tricks for a beginner it would be greatly appreciated!

I’ve done a DMARC report check btw, but is there anything else I can do?
