Hello Peter,
thank You for your Responds.

I thougth so too, but it doesn't.
Is there anything i have to change somewhere to get the wildcards working?

>Please update your schema to allow the NULLs!
We use a custom made Program, to manage our Zones, which get Errors if the Type get's NULL, that's why i wanted to Use the Wildcard and just add PTR's with the content "hosted.by.xxxx".
I'll try to look into the program to find a way for a solution for Problem with the NULL Constraint.
But until i found one, i would like to use the wildcard.

Kind regards,

There is nothing special about PTRs, and you can wildcard them according to the same rules as any other record.

This should work.

This does not work.

Please update your schema to allow the NULLs!
