Has anyone try to go the site.

it gets redirected to:

http://107.170.104.233/online/

Says secure payment on a NON-SSL site. Sounds pretty shady.

Can you name a legit site for the general public that doesn't even have a domain name?

1.1.1.1 does have a domain name (and of course is operated by Cloudflare) but it doesn't redirect you or anything, it's totally happy to advertise itself as https://1.1.1.1/ which seems more memorable than most possible names.

Yes the DNS companies are an exception because the number is meaningful to humans.
