In this guide, we’ll explain what CDNs are, why they’re used, and provide a detailed overview of the various methods you can use to locate the origin IP behind CDNs.

Backend CDN

What are CDNs?

Content Delivery Networks (CDNs) are networks of servers distributed across the globe, designed to store and distribute web content to users in a faster, more efficient manner. CDNs work by replicating web content across multiple servers, so that users can access it from the server that’s closest to them, reducing latency and improving website performance.

Why are CDNs Used?

CDNs are used for a variety of reasons, including:

  1. Faster website load times: By caching web content on multiple servers, CDNs reduce the time it takes for users to access web content, resulting in faster website load times.
  2. Improved website performance: CDNs help to reduce latency, resulting in improved website performance and user experience.
  3. Increased website availability: By replicating web content across multiple servers, CDNs help to ensure that websites remain available even if one or more servers go down.
  4. Reduced server load: By distributing web content across multiple servers, CDNs help to reduce the load on individual servers, improving their overall performance.

Websites Origin IP 

Whenever you enter a website’s domain name into your browser, the Domain Name System (DNS) translates that name into an IP address that points to the website’s server. This IP address is known as the Origin IP and it is where all of the website’s content is stored and served from.

However, the Origin IP is more than just a birthplace; it is the beating heart of your website. It’s where all of your website’s code, images, videos, and other content are stored and managed. Without the Origin IP, your website would simply not exist.

Just like every person has a unique birthplace, every website has its own unique Origin IP. It is what sets your website apart from every other website on the internet.

However, the Origin IP is also vulnerable to attacks. Hackers and cybercriminals often try to exploit vulnerabilities in your server to gain access to your website’s content. This is why it is vital to safeguard your Origin IP with robust security measures, such as firewalls, anti-virus software, and regular backups.

Methods to find Origin IP of a website?

Finding the Origin IP of a website can be a tricky task, but there are a few methods that can be used to accomplish this goal. Here are two different approaches:

Reverse Engineering

One way to find the origin IP of a website is through reverse engineering. This involves analyzing the website’s code and network traffic to determine where the content is being served from. Some tools that can be used for this purpose include traceroute, nslookup, and whois.

Using these tools, a skilled analyst can map out the network infrastructure and trace the traffic back to its source, which should be the Origin IP of the website. This approach requires a lot of technical expertise and may not always be reliable, but it can be effective in certain situations.

Protections Blue Teamers provide

On the other hand, Blue Teamers work to protect the Origin IP of a website by implementing security measures that make it harder for attackers to find it. This can include techniques such as hiding the server behind a Content Delivery Network (CDN) or using load balancing to distribute traffic across multiple servers.

By implementing these protections, Blue Teamers make it more difficult for attackers to launch DDoS attacks or other types of cyber attacks that could disrupt the website’s availability or compromise its security. Additionally, they can use tools such as firewalls and intrusion detection systems to monitor and block suspicious traffic before it reaches the Origin IP.

Back to Attacker Side 

As an attacker, the ability to find the origin IP of a website is a crucial step in launching successful cyber attacks. Here are some of the methods and techniques that attackers might use to carry out this task: 

1. DNS reconnaissance 

DNS reconnaissance is a technique used by attackers to gather information about a target website’s DNS records, including its IP address and other critical information.

To carry out DNS reconnaissance, an attacker first identifies the target website’s domain name and determines the DNS servers that are responsible for resolving its domain name. They then query the DNS servers using the appropriate tool to retrieve the website’s IP address and other DNS records.

For example, an attacker may use the nslookup command to query the target website’s DNS server and retrieve its IP address:


This command will return the IP address associated with the domain name, which is the Origin IP of the website.

In addition to retrieving the IP address, attackers may also use DNS reconnaissance to gather other critical information about the website’s infrastructure, including its domain name registrar, DNS records, and other network configuration details. Armed with this information, attackers can launch more targeted and sophisticated cyber attacks, including DDoS attacks, phishing campaigns, and malware infections.

2. Network scanning

Network scanning is a technique used by attackers to identify the network infrastructure of a target website and identify potential vulnerabilities that can be exploited in a cyber attack. This technique involves using specialized tools like nmap or masscan to scan the target website’s network for open ports, services, and other potential security weaknesses.

To carry out a network scan, an attacker first identifies the IP address or range of IP addresses associated with the target website’s network. They then use a network scanning tool like nmap or masscan to scan the network and identify open ports, services, and other potential vulnerabilities.

For example, an attacker may use the nmap command to scan a target website’s network for open ports and services:

nmap -sS

This command will scan the website’s network using a TCP SYN scan and identify any open ports and services that can be exploited in a cyber attack.

Once the attacker has identified potential vulnerabilities, they can use this information to launch more targeted and sophisticated cyber attacks, including network intrusion, data theft, and DDoS attacks.

 3. Social engineering 

Social engineering is a technique used by attackers to manipulate and deceive individuals into divulging confidential information, such as login credentials, financial information, or other sensitive data. This technique involves exploiting the trust, naivety, and vulnerabilities of individuals to gain access to sensitive information or systems.

To carry out social engineering attacks, attackers conduct extensive research on their targets, including their personal and professional backgrounds, interests, and vulnerabilities. They use this information to craft targeted and convincing messages that are tailored to their targets’ interests and needs.

4. Malware and phishing attacks 

Malware and phishing attacks are two of the most common types of cyber attacks that threaten individuals and organisations worldwide. These attacks use malicious software or fraudulent messages to gain unauthorised access to computer systems, steal sensitive information, or disrupt critical operations.

Malware attacks involve the use of malicious software, such as viruses, worms, or Trojans, to infiltrate computer systems and steal sensitive information.

Phishing attacks, on the other hand, involve the use of fraudulent messages, such as emails or text messages, to trick individuals into divulging sensitive information, such as login credentials or financial information.

To protect against malware and phishing attacks, individuals and organisations should implement strong security measures, including firewalls, antivirus software, and other tools that can detect and block malicious traffic. They should also regularly update their software and operating systems to patch known vulnerabilities and stay current with the latest threats.

Additionally, individuals and organizations should educate themselves and their employees about the various types of malware and phishing attacks and how to identify and avoid them. This includes being cautious when opening unsolicited emails or messages, avoiding clicking on suspicious links or downloading attachments from unknown sources, and using strong passwords and two-factor authentication to protect sensitive accounts.

By staying vigilant and taking proactive steps to protect against malware and phishing attacks, individuals and organisations can reduce their risk of becoming victims of cyber attacks and protect their sensitive information from theft or compromise.
