How to Detect Business Fraud

I don't think they actually use cloudflare. Neither their nameservers nor their server IPs are cloudflare. They only copied their interstitials.

They are for me, apparently because I'm using cloudflare's DNS service, and cloudflare is returning its own IP when I query for archive.vn's.

  $ dig +short @8.8.8.8 archive.vn 
  5.196.68.232
  $ dig +short @1.1.1.1 archive.vn       
  1.0.0.1
  1.1.1.1

They don't return themselves for all hosts,

  $ dig +short @1.1.1.1 google.com
  172.217.9.14

I wonder by what criteria they intercept, and if this by archive.vn's or cloudflare's initiative.

This link should answer your questions and give the backstory.
