Scrapebox footprint help please

Hi.

I would like to ask if someone knows how to scrape for example all the subdomains from thedomain.com and the harvested results are :

1) one.thedomain.com
2) two.thedomain.com
3) three.thedomain.com
4) xxx.thedomain.com
5) abc.thedomain.com

NO other urls..

Thanks :)
