Unknown Subdomains Ranking

[JordanNCU]

In spot checking some pages that I recently launched, I found subdomains ranking in place of the domain. The strange thing is, we never set up these sub-domains and they don't exist on our server. The pages, though they're indexed with the proper title and meta-description, time out when clicked.

We're operating on Drupal 7, pages launched at the beginning of the month. The other pages within the series of content are ranking properly. Any thoughts or tips to resolve this?

Have you tried removing them in Search Console?

I haven't yet, and I'm hoping to solve the bigger issue first I suppose.

Essentially, i built the content on www.domain.com, the canonical tag is correct.

www.UnknownSubdomain.domain.com is what's showing up in rankings. The entire URL structure of the ranking domain makes no sense. We have no record of the subdomain being created, when i ping the random URL I get our host ip. I'm working on creating the property in search console and will try to block it from there.
