How to Find Real IP Address of Website Using Cloudflare

When you access a website, sometimes you will find the page mentioned Cloudflare before redirected to the landing page. Cloudflare is a CDN (Content Delivery Network) whose work is to host your website static contents in its server and this static content is then served to your website visitors.

Some websites use them as a full proxy, protect your website address by changing your website address IP, making your website less vulnerable from attacks.

An IP address is an Internet protocol address, a numerical label assigned to all devices participating in Internet Protocol communication. It is unique for each device. Checking an IP address for a website isn’t hard to do.

How to Check IP Address of a Website

You can simply open your command prompt, or terminal or Termux and type in:

ping example-domain-name.com

You can also use nslookup command if you’re a Windows user. For example, if you want to know the IP address of google.com just open your command prompt then type in:

nslookup google.com

The result will look like this:

nslookup google.com
Server: UnKnown

Non-authoritative answer:
Name: forcesafesearch.google.com
Addresses: 2001:4860:4802:32::78
Aliases: www.google.com

As you see there are two IP addresses there; 2001:4860:4802:32::78 and The first one is the newer version of the IP protocol, IPv6. The second one is the older version IPv4.

Sometimes, huge websites such as Google use more than one IPv4 address because it shares millions of visitors across their servers.
