Incorrect clearing of wildcard subdomains.

[Phoenix1112]

thanks for this project.

example:

drive.example.com
blabla1.drive.example.com
blabla2.drive.example.com
blabla3.drive.example.com

Imagine that the above subdomain addresses are in a list. When shuffledns cleans up the wildcard subdomains above, it also cleans drive.example.com. the real problem here is that the wildcard starts after *.drive.

shuffledns should only show this domain as a result. drive.example.com
The following are the wildcard subdomains that need to be deleted.

blabla1.drive.example.com
blabla2.drive.example.com
blabla3.drive.example.com

The http status codes of the above subdomain addresses were as follows.

drive.example.com 200
blabla1.drive.example.com 403
blabla2.drive.example.com 403
blabla3.drive.example.com 403
adksfdhjklsjkhldfkjhasdjklajklhasjkld.drive.example.com 403

so when clearing wildcards, you need to detect where the wildcard starts.

Here is a sample subdomain address for you to test.

games.mail.ru
blabla.games.mail.ru
api.games.mail.ru
