    There is an option (way) to disable wildcard subdomain creation, like *.domain.com ?

    I don't know if I am in the good forum.

    As far as I know, root user will be having privilege to create wilcard DNS entries.

    If you simply want to remove the wild card record of a domain, you may remove the corresponding entries from the apache configuration file ( ServerAlias in VirtualHost entry) and DNS zone file (*.domain.com ).

    Else, if you are talking about disabling the creation of such wild card records by root, it is not possible because, root user is having full privilege to edit these files (in my point of view).

    However, you can limit the options available for a Cpanel user, from the FeatureManager in WHM.

    cp.jpg I am sorry, maybe I didn't explain correctly. So a user created a subdomain [*.domain.com] with directory [/home/user/public_html]. Is it possible to limit or block any * in the subdomain field?

    Thank you.

    Interesting. Adding a single asterisk is ok, but 2 is not, nor as in my picture above, is *.* allowed.

    I would consider this a bug to be honest. Someone much smarter than I might have a more proper answer to this, but mine is, you should open a Defect report on this one, here:
    http://go.cpanel.net/bugs

    When you do, please feel free to link to this thread in that report you make.

    Thanks!

    I don't think so is a bug, that's why I don't know if I have to submit this like a bug. This is used in "WordPress Multisite". I have seen this on youtube.com (I don't want to put here the link because there is a name of a webhosting company there).

    Regards
