Block wildcard subdomains

Hello, i’ve an application that send private data by connecting each time to random subdomains , example , is there a way to block * ? The ip associated with these subdomains change often so entering the ip directly is not a viable solution.

Thank you

7 years later and we are still at the same place !! no solution for this simple option !!

I hope this problem is resolved before I die… I hope I can use it even for one day only!

Tell them the number of days you have left so they can add it to their planning on the day number minus 1 … lol :slight_smile:

;D ;D
Maybe it is the only way to convince them to do it at the end :wink:

Am I dreaming?
Was this problem fixed in the latest version v12.2.2.7062?

I’ve tried to block a “Host Name” (without *), and it actually blocked the domain and all its sub-domain names !! :slight_smile: :slight_smile:
Thank you very much Comodo team :-TU :-TU :-TU :-TU :-TU

No it is not possible to use wildcards when creating a hostname type rule and so you are seeing the over blocking issue as I have explained in another thread:

Oh, I see…
Thank you for the clarification.
