how to use python to check if subdomain exists?
Do a curl or http request on subdomain which you want to verify, if you get 404 that means it doesn't exists, if you get 200 it definitely exists
Does anyone know how to check if a subdomain exists on a website?
I am doing a sign up form and everyone gets there own subdomain, I have some javascript written on the front end but I need to find a way to check on the backend.
