Resolved All possible subdomains subxxx.domain.ltd are pointing to domain.ltd and www.domain.ltd

[Jürgen_T]

Server operating system version

Ubuntu 20.04.5 LTS

Plesk version and microupdate number

Plesk Obsidian v18.0.49

I upgraded from Plesk V. ...48 to Plesk ...49. Now I found out by chance, that a deleted subdomain subXXX.domain.de is now pointing to www.domain.de . After discovering this I also found out that ALL possible subXXX.domain.de are pointing to www.domain.de.

I am afraid that this could harm my SEO.

How can I make sure that not any subdomain subxx.domain.com points to my main domain www.domain.de or domain.de ?

This scenario is the case when your domain.de is also your host domain. You could create a wildcard subdomain * (*.domain.de) and put a page on that or redirect that to another target of your choice.

Thank you. Will this solve my problem, that currently test.domain.de (which does not exist) points to www.domain.de (what I do not want)?

I just did it and ... it works! Thank you for your quick help
