For eg. I want to know all the google websites So, on this website I searched for google.com and I get 61 domains.
But in that I missed one website which is https://research.google.com So, when I type this website, I got 62 domains.
Why is it so and how to get all the websites under single webserver.
Do you want to list the different domains or the subdomains as well?
If you want to display the subdomains as well, you can take a look here: https://security.stackexchange.com/q/35078/18541
