Wondering what DDoS Protected IP is? Engineer C7 breaks down the DDoS protection system—covering attack mechanisms, traffic scrubbing, protection processes, and enterprise use cases—while comparing top providers like Cloudflare, Akamai, AWS, and CDN07 to help you choose the best solution for global and China-facing businesses.

1. Why Should You Understand DDoS Protected IP?

In 2025, cyber attacks have become one of the core threats to business stability.

Whether you run an e-commerce store, online game service, API platform, or even a simple content site—if you have traffic and competition, you're at risk of:

• DDoS Attacks
• HTTP Flood
• SYN Attacks
• CC Attacks
• Connection Exhaustion
• Malicious Traffic from Black/Gray Markets

The goal is always the same:

To make your service unavailable, take your site offline, and halt your business operations.

Among all protection methods, the most effective and widely recommended is DDoS Protected IP (High Defense IP).

But many users only know it's "powerful"—without understanding how it works or how it differs from a regular IP.

This guide will help you fully grasp:

How does a Protected IP keep your website safe from attacks?

2. What Exactly is a DDoS Attack? Why Can’t Normal Servers Handle It?

DDoS (Distributed Denial of Service), known in Chinese as “分布式拒绝服务攻击”.

Simply put:

Attackers use thousands of hijacked devices (botnets) to flood your server with useless requests, exhausting its resources so it can’t serve real users.

A single DDoS attack can cause—within seconds:

• CPU to spike to 100%
• Bandwidth saturation
• Connection overload
• Server unresponsiveness
• Website downtime
• Loss of customers
• Drop in SEO ranking
• ISP blocking your IP

So why can’t normal servers cope?

Ordinary servers have limited bandwidth.

A typical dedicated server offers:

• 10Mbps
• 50Mbps
• 100Mbps

But a typical attack can reach:
10 Gbps, 100 Gbps, 300 Gbps, or even over 1 Tbps.

Your bandwidth gets overwhelmed instantly.

3. What is DDoS Protected IP? Explained in One Sentence

DDoS Protected IP = A specialized IP with massive bandwidth + traffic scrubbing system + intelligent protection policies.

To put it simply:

Normal IP = Gets knocked out when attacked

Protected IP = Absorbs, scrubs, and filters attack traffic, then forwards clean traffic to your origin server

It doesn’t stop attacks from happening—it neutralizes them.

4. What Are the Core Capabilities of a DDoS Protected IP?

1) Massive Bandwidth Capacity

Normal servers have tens or hundreds of Mbps.

Protected IPs offer much more:

• 500 Gbps
• 800 Gbps
• 1 Tbps
• Multi-Tbps scrubbing clusters

The bigger the scrubbing capacity, the more attack traffic it can absorb.

2) Automatic Traffic Scrubbing (Auto Mitigation)

As soon as an attack is detected, the system:

• Identifies the attack type
• Applies layered filtering
• Dynamically adjusts rules
• Ensures legitimate traffic flows uninterrupted

Attacks are blocked in milliseconds.

3) Multi-Vector Attack Protection

Covering major attack types like:

• UDP Flood
• TCP SYN Flood
• ACK Flood
• ICMP Flood
• HTTP/HTTPS Flood (CC)
• DNS Query Flood
• Application Layer attacks
• Mixed large/small packet attacks

Different providers excel in different areas:

• Cloudflare → Strong L7 protection
• Akamai → Top-tier global traffic capacity
• CDN07 → Specialized DDoS protection for Mainland China & Asia Pacific

4) Origin IP Masking – Prevent Direct Hits

The Protected IP acts as a shield:

Attack traffic → Hits the Protected IP

Clean traffic → After scrubbing → Sent to your origin server

Your real server IP stays hidden.

5) AI Learning & Rule Optimization

The system continuously learns your traffic patterns:

• Normal user browsing behavior
• Typical API response patterns
• Peak connection thresholds
• Token, Cookie, User-Agent, and Header characteristics

Making protection smarter over time.

5. Top 5 DDoS Attacks Enterprises Face

① SYN Flood

Fake TCP connection requests overwhelm server connection tables.

② UDP Flood

Floods the server with junk packets using connectionless protocols.

③ CC (HTTP Flood) Attack

Mimics normal visits—but at superhuman frequency.

④ Hybrid Attacks (L3 + L4 + L7)

The most challenging and common type.

⑤ DNS Query Flood

Makes your domain unresolvable.

6. How Does DDoS Protected IP Work? Step-by-Step Process

Here's the standard protection flow:

① Attack Traffic Enters the Scrubbing Center

At the protection node, traffic is split:

• Malicious traffic → Scrubbed & dropped
• Clean traffic → Forwarded to origin

② Scrubbing System Uses Multiple Filtering Techniques

Including:

• Signature-based detection
• Behavioral analysis
• Connection limiting
• Rate limiting
• JS Challenge (e.g., Cloudflare)
• CAPTCHA
• Bot detection
• IP reputation database
• Deep Packet Inspection (DPI)
• Blackholing (temporarily dropping traffic during extreme attacks)

③ Clean Traffic is Forwarded to Your Server

This step is critical:

Attack traffic → Handled by the Protected IP

Legitimate visits → Routed securely to your origin

Your server stays safe from attack pressure.

• Dedicated protection for cross-border, gaming, live streaming, API, and transactional sites
• Tbps-level scrubbing
• Supports Protected IP, global CDN, hybrid access
• No real-name verification required
• Accepts USDT payments

For global e-commerce, gaming, and cross-border sites:

Use Cloudflare for global traffic, and CDN07 for China-facing stability and protection.

📌 Overseas & Mainland China Acceleration / Protection Comparison

Green = clear advantage, --- = not supported or weak performance.

Summary Table Takeaways

• If your users are mostly in the West and don’t need China access: Cloudflare / Akamai are best.
• If you run API-heavy or developer-focused services: Fastly is stronger.
• If you’re fully on AWS: CloudFront is the natural choice.
• If you need "Overseas-to-China" or "China-to-Overseas" routing + face frequent attacks:
  CDN07 fits best, since most global providers don’t optimize for China networks or offer China-grade DDoS protection.

8. Which Businesses Must Use DDoS Protected IP? (Very Important)

If you’re in any of these industries, you’re almost 100% likely to be attacked without protection:

• Game login/payment gateways
• Video/live streaming platforms
• International e-commerce
• Sports, betting, or lottery sites
• API servers
• Financial systems
• Transaction-related services
• Competitive business websites
• Crawler-sensitive applications

Especially if your users are in Mainland China, Southeast Asia, South Korea, or Taiwan:

The risk of DDoS attack is extremely high.

9. How Should Businesses Choose a DDoS Protection Service?

Here’s a practical way to decide:

① Know Your User Geography

• Mostly overseas users → Cloudflare + CDN07
• Mostly China users → Definitely use CDN07 Protected IP

② Check If You're Already Under Attack

Frequently attacked → Must deploy Protected IP now

Not attacked yet, but growing fast → Better to protect early

③ See If You Need Cross-Border Optimization

If you:

• Host servers overseas
• But need fast access from Mainland China

Then:

CDN07 is one of the few providers offering "Overseas → China optimization + DDoS protection" together.

10. Protected IP is Essentially an "Elastic Shield" for Your Business

In a nutshell:

The value of a Protected IP isn’t whether you get attacked—it’s ensuring attacks never impact your business.

For Asia Pacific and China-included user bases, relying only on Western CDNs is not enough:

Cloudflare, Akamai → Strong overseas

CDN07 → Strong in China + Asia Pacific protection

Using both is the complete architecture.
