In today’s connected world, IP addresses are the foundation of internet communication. Every device that connects to the internet — from your smartphone to a web server — uses an IP address to identify itself and exchange data.
With the exhaustion of IPv4 addresses and the rise of new technologies, the world is gradually moving toward IPv6. However, both IPv4 and IPv6 proxies continue to play vital roles in networking, data scraping, and online automation.
Let’s explore what they are, how they differ, and why Scrapeless Proxy supports IPv6 proxies for ultimate flexibility and performance.
What Is an IP Address?
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a network.
It serves two main purposes:
- Identification: It identifies a specific device or network interface.
- Location: It helps route data between the device and the rest of the internet.
Think of it as a digital “home address” for your device — when you send or receive information, the IP address ensures it reaches the right destination.
What Is IPv4?
IPv4 (Internet Protocol version 4) is the fourth version of the Internet Protocol and has been the backbone of the internet since the early 1980s.
IPv4 addresses are 32-bit numbers, typically written as four sets of numbers separated by dots — for example, 192.168.1.1.
Because it uses 32 bits, IPv4 provides around 4.3 billion unique IP addresses. This seemed sufficient decades ago, but with the explosion of connected devices (smartphones, IoT, cloud servers, etc.), IPv4 addresses are running out.
Key Characteristics of IPv4:
- 32-bit address format
- Approximately 4.3 billion possible addresses
- Simple and widely compatible
- Uses NAT (Network Address Translation) to manage limited IP space
What Is IPv6?
IPv6 (Internet Protocol version 6) is the next-generation IP protocol developed to solve the limitations of IPv4.
IPv6 addresses are 128-bit numbers, expressed in hexadecimal format — for example:
2001:0db8:85a3:0000:0000:8a2e:0370:7334.
This structure provides an almost unlimited number of unique IP addresses — approximately 340 undecillion (that’s 340 followed by 36 zeros).
Key Characteristics of IPv6:
- 128-bit address format
- Virtually unlimited address space
- Built-in encryption and security features
- Better routing efficiency and mobility support
What IPv4 and IPv6 Have in Common
Despite their differences, IPv4 and IPv6 share several similarities:
- Both identify and locate devices on a network.
- Both support TCP and UDP protocols.
- Both can be used to route internet traffic, including proxy services.
- Both play a crucial role in data scraping, web automation, and privacy protection.
In short, they serve the same purpose — but IPv6 offers a modern, scalable foundation for future growth.
Why We Moved from IPv4 to IPv6
The main reason for transitioning to IPv6 is address exhaustion.
With billions of devices connecting daily, IPv4 simply doesn’t have enough addresses left. IPv6 was designed to fix that, providing:
- Vastly more unique IPs
- Simplified network configuration
- Enhanced security features (like IPsec support)
- Improved packet processing and routing
However, migration to IPv6 has been slow because of compatibility issues, legacy hardware, and the widespread use of NAT with IPv4.
The Benefits of IPv6 Over IPv4
| Feature | IPv4 | IPv6 |
|---|---|---|
| Address Space | ~4.3 billion | ~340 undecillion |
| Header Complexity | Complex | Simplified |
| Security | Optional (IPsec) | Built-in (mandatory IPsec) |
| Configuration | Manual or DHCP | Auto-configuration supported |
| Routing Efficiency | Less efficient | More efficient |
| Performance | Moderate | Faster in peer-to-peer and modern systems |
Additional IPv6 Advantages:
- No NAT dependency: Each device can have its own public IP.
- Improved mobility: IPv6 simplifies device switching between networks.
- Better performance for automation: IPv6 proxies offer faster, cleaner connections with lower risk of detection.
Why IPv6 Is Still Not Fully Adopted
Despite its benefits, IPv6 adoption remains partial. The main reasons include:
- Legacy Infrastructure: Many organizations still rely on IPv4-based systems.
- Cost of Transition: Upgrading hardware and software to IPv6 can be expensive.
- Compatibility Issues: Some applications or ISPs don’t fully support IPv6.
- Dual-Stack Operations: Most networks use both IPv4 and IPv6 simultaneously, slowing the transition.
Nonetheless, IPv6 usage continues to grow, and proxies like Scrapeless IPv6 Proxy make it easier for businesses to adapt while maintaining performance.
IPv4 vs IPv6 Proxies in Practice
Both IPv4 and IPv6 proxies serve similar goals — privacy, data access, and automation — but they differ in scalability and efficiency.
IPv4 Proxies
- Best for compatibility with older sites
- Stable but limited IP pool
- Higher cost due to scarcity
IPv6 Proxies
- Massive IP pool — perfect for high-volume automation
- Lower cost per IP
- Faster, modern protocol support
