IPv4 and IPv6 are two distinct protocols used for data transmission over the internet. Both have their own characteristics and benefits, making it crucial to understand how they differ from one another.
IPv4
Developed in 1981, IPv4 is the most widely used protocol on the internet today. It uses 32-bit addresses, which allow for around 4 billion unique IP addresses.
IPv6
IPv6 is a newer protocol developed in 1998 to replace IPv4. It utilizes 128-bit addresses, providing approximately 340 trillion unique IP addresses. This is a significant increase over IPv4, offering a practically limitless number of addresses for devices worldwide.
Despite its larger address space, the transition to IPv6 has been slow due to the need for updating network infrastructure and software. Additionally, some internet service providers (ISPs) do not yet support IPv6, which may cause issues when using proxy servers.
Why Update from IPv4?
IPv4, designed in the 1980s, became an essential part of internet connectivity by assigning each device a unique IP address. However, by 2007, it was clear that 4 billion addresses were not enough.
IPv4 also faced other limitations, such as inefficient routing, which strained router performance.
With the rise of bandwidth-intensive applications like video streaming and conferencing, the demand for a more efficient solution grew. Consequently, IPv6 was introduced as a more flexible and scalable protocol.
Differences Between IPv4 and IPv6
IPv4 and IPv6 are versions of the Internet Protocol (IP) responsible for data packet routing online. They have several critical distinctions that affect their functionality and capabilities.
Address Length
IPv4 addresses are 32 bits long, allowing for up to 4.3 billion unique addresses. As the number of internet-connected devices grew, this became insufficient. IPv6, with its 128-bit addresses, provides a vastly larger number of unique addresses, ensuring sufficient availability for every device globally.
Address Format
IPv4 addresses are written in dot-decimal notation as four groups of numbers ranging from 0 to 255 (e.g., 192.168.1.1). IPv6 addresses, in contrast, are written in hexadecimal format as eight groups of four characters separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
Subnetting
IPv4 uses subnet masks to divide address spaces into smaller blocks, enhancing flexibility and address management. IPv6 also supports subnetting but operates differently. Instead of subnet masks, IPv6 uses a specific part of the address to designate the subnet.
Security and Authentication
IPv6 offers stronger security and authentication features than IPv4. For instance, IPv6 supports IPsec natively, providing data encryption and secure authentication for transmitted data.
Traffic Management
IPv6 has improved traffic management capabilities compared to IPv4. It includes features like multicast transmission, allowing data to be sent to multiple recipients simultaneously, improving efficiency.
Transitioning to IPv6
The shift from IPv4 to IPv6 is a gradual but necessary process. While many new devices and networks already support IPv6, full adoption will take time. If your current system supports IPv4, switching to IPv6 might not be immediately necessary. However, for long-term compatibility and integration with emerging technologies, transitioning to IPv6 is advisable.
How to Check if a Website Supports IPv6
There are several methods to verify IPv6 support for a website:
Online Tools
Many online tools, like the IPv6 check tool from Belurk, allow users to check if a website supports IPv6. Simply enter the site’s URL and click “Check” to see the results.
Command Line
You can check IPv6 support using the “ping6” command. Open a command prompt (e.g., press “Win+R” and type “cmd” in Windows) and enter “ping6 -c 1 example.com.” If the site supports IPv6, you’ll receive a response.
Browser Tools
Some browsers, such as Google Chrome, have built-in tools for checking IPv6 compatibility. Open “Developer Tools” (Ctrl+Shift+I), go to the “Network” tab, and refresh the page. Select “IPv6” in the dropdown menu to see if any IPv6 requests are being made.
It’s important to understand that while a website may support IPv6, it doesn’t guarantee that all its features will function correctly. Some sites might use IPv6 for specific functions or subdomains only.
Why Choose IPv6?
Opting for IPv6 has several advantages:
IPv4 Address Exhaustion
IPv4 addresses are fully depleted, and no new addresses can be allocated. As a result, more devices will eventually struggle to get IPv4 addresses. IPv6’s vast address space solves this problem.
Improved Security
IPv6 includes advanced authentication and encryption features, such as IPsec support, which enhance data security.
Enhanced Traffic Management
IPv6 supports efficient traffic management, including multicast capabilities for sending data to multiple recipients simultaneously.
Compatibility with Emerging Technologies
New technologies like the Internet of Things (IoT) require numerous unique IP addresses. IPv6 has enough addresses to accommodate these demands.

IPv4 and IPv6 Proxies: Choosing the Right Option
IPv4 and IPv6 proxies each have unique advantages. Although IPv4 proxies are based on older technology, they remain popular due to their simplicity and availability. On the other hand, IPv6 proxies offer more modern benefits, including a larger address range, enhanced security features, and better efficiency.
IPv6 proxies may also be more resistant to blocking attempts and provide a higher level of anonymity. Choosing between IPv4 and IPv6 proxies depends on individual requirements and preferences.
