We did this for a customer and to see what leaks. It’s very surprising and sometimes very bad from a security perspective on popular and high traffic domains of service providers.
I remember when this hit HN a few months(?) back, for me it was the first time learning about this and I assumed this might be an obscure thing.
I ran the python script against my (very large) employer's domain name and was pleasantly surprised to see we owned all the bitsquatted versions already (there were maybe 10?)
