Thank you for your reply and explanation, @UnknownLolz; much appreciated.
So it’s an InfinityFree thing? My confusion was that I was getting these when the name servers weren’t set to IF. I’ll try to configure a subdomain, and as long as that works fine, I’m happy.
Well any subdomains that doesn’t exist under your domain (and by that I mean subdomains that you did not create) will still show a page like what you saw here on InfinityFree’s platform even if your domain is using InfinityFree’s nameservers.
Are you using Cloudflare nameservers by any chance? And did you use their automatic record scanning to set up your domain name?
If so, you’ll likely have a CNAME record which points to 11776.BODIS.com on your domain. That’s the record from the parking service we use. You can safely remove that one.
