Unknown sub domain

hello

I receive a notification about certification that is about to expire but I don’t know this subdomain: wp53
the full domain is: wp53.moonloop-records.com

I have the domain : moonloop-records.com hosted on my server but not the subdomain

Can someone explain what this is ?

thanks, regards

sacha

Hi @sAco2web

checking your domain there are a lot of older certificates with different configurations - https://check-your-website.server-daten.de/?q=moonloop-records.com#ct-logs

A Letsencrypt certificate - 2017-02-28 08:20:00.

A lot of cPanel - 2017-06-21 06:51:00.

Then Letsencrypt with three domain names - 2019-03-25 12:36:23.

And some active certificates:

Staging is defined, wp53 not.

You have your own name server ns1.moonloop-records.com. Did you use other name servers? There are some free hoster, there it’s possible that everyone can create subdomains if the domain is registered.

Thanks for help. Issue is solved. Had dns entry… thanks
