Cloudflare appears on the list because it's impossible for HostCabi to know which actual provider hosts Cloudflare protected sites. Once someone puts their site on Cloudflare, there's no way to know what their IP/provider/etc is. That's the point of it.
Impossible? Impossible is a challenge

I wonder who 198.58.111.238 is?

Non-authoritative answer:
238.111.58.198.in-addr.arpa name = li607-238.members.linode.com.
Authoritative answers can be found from:
111.58.198.in-addr.arpa nameserver = ns4.linode.com.
111.58.198.in-addr.arpa nameserver = ns1.linode.com.
111.58.198.in-addr.arpa nameserver = ns3.linode.com.
111.58.198.in-addr.arpa nameserver = ns5.linode.com.
111.58.198.in-addr.arpa nameserver = ns2.linode.com.
You can get rid of the direct link but most people don't. Also asking netcraft tends to work.
