Question 1

What is Cloudflare mainly used for?

Accepted Answer

Cloudflare provides services including authoritative DNS, reverse proxying, content delivery, application security, network connectivity, Zero Trust, and developer compute and storage.

Question 2

Is Cloudflare only a CDN or DDoS service?

Accepted Answer

No. CDN and DDoS protection are parts of a broader platform that also covers DNS, application security, networking, workforce access, compute, and data services.

Question 3

Can a domain use Cloudflare DNS without proxying its website?

Accepted Answer

Yes. A DNS-only record uses Cloudflare for authoritative DNS while visitors connect to the configured destination. A proxied record sends supported traffic through Cloudflare first.

Question 4

Does a Cloudflare IP reveal a website's hosting provider?

Accepted Answer

Usually not. For a proxied hostname, the visible address belongs to Cloudflare's public network path and does not reliably identify the origin server or hosting provider.

Question 5

Does every website using Cloudflare cache its pages?

Accepted Answer

No. Cache behavior depends on the product, request, response, rules, and customer configuration. Proxying alone does not prove that a response was cached.

Question 6

What is the difference between public application security and Zero Trust?

Accepted Answer

Public application services protect Internet-facing sites and APIs. Zero Trust and SASE services control how employees, devices, and networks reach private resources, the Internet, and software services.

Question 7

Does Cloudflare make a website completely secure?

Accepted Answer

No. Cloudflare supplies infrastructure and security controls, but application code, identities, permissions, origins, data handling, monitoring, and incident response still require careful operation.
