WordPress Multisite Subdomain

[Mushlih]

Is it possible in infinityfree free hosting to create WordPress multisite with subdomains? If yes how I add a DNS wildcard?
I use free hosting and free sub domain on this hosting.

Is this what you are looking for?

How can i run the same WordPress install on multiple subdomains?

[Mushlih]

Yes, but is it possible on this hosting?
Because I have to create wildcard DNS to implement it.

No.
This should answer your question

The WPMU

WordPress multisite will not work on free hosting, especially if you want to use subdomains (subdirectories might work). As you suspected, the configuration files you need to edit are hidden inside the servers and you cannot edit them yourselves (since that’s where we create the accounts for people). However, you can create wildcard subdomains on premium hosting, so you may wish to consider to upgrade your account.
