The Main Differences Between IPV4 and IPv6
At their core, IPv4 and IPv6 are like two generations of a technology dynasty. IPv4, the elder, uses a 32-bit numeric system, allowing it to create roughly 4.3 billion unique addresses. Meanwhile, IPv6, the modern heir, ups the game with a 128-bit hexadecimal method, capable of producing an astronomical number of unique addresses, over 340 undecillion to be precise.
This is more than enough to address every device on Earth for many years to come.
Beyond sheer numbers, the main differences between the two is as follows:
Address Size and Structure
- IPv4: 32-bit numeric address.
- IPv6: 128-bit hexadecimal address.
Total Address Capacity
- IPv4: Roughly 4.3 billion unique addresses.
- IPv6: Over 340 undecillion unique addresses. That’s 340 followed by 36 zeros!
- IPv4: Contains various fields, making its header more complex.
- IPv6: Simplified header designed for efficient data transmission.
- IPv4: Can be configured either manually or through DHCP.
- IPv6: Can automatically assign itself an IP address.
- IPv4: Sends data to every device in a subnet, even if only one needs it.
- IPv6: More selective, sending data only to devices that require it.
IP Address Management and Re-use
- IPv4: Due to limited addresses, often uses techniques to reuse IP addresses.
- IPv6: With its vast number of addresses, there’s typically no need to reuse them.
- IPv4: Doesn’t handle mobile IP scenarios as efficiently.
- IPv6: Improved support for mobile IP and is better suited for modern mobile networks.
Considering the Cost Factor
The choice between IPv6 and IPv4 isn’t solely based on technical specifications. The cost implications, especially for businesses, play a pivotal role in driving decisions. Let’s break down the cost dynamics of both proxy types to help businesses gauge which offers better value.
IPv6 Proxies Costs
Initial Setup Costs
Deploying IPv6 might involve updating or replacing some existing infrastructure components to be IPv6 compatible.
While this might mean an upfront cost, businesses need to see this as an investment for future-proofing their operations.
Address Abundance = Lower Costs
Given the vast address space of IPv6, the cost per IP is generally lower than IPv4. This makes bulk acquisitions for large-scale operations more cost-effective.
Maintenance & Management
As a modern architecture, IPv6 might offer cost savings in terms of long-term maintenance.
However, businesses might face a steeper learning curve and might need to invest in training or hiring specialists initially.
IPv4 Proxies Costs
Rising Prices for a Dwindling Resource
As IPv4 addresses become scarcer, their market price has surged. Acquiring new IPv4 addresses, especially in bulk, can be significantly more expensive.
Given its long-standing presence, many businesses already have an established IPv4 infrastructure.
This means fewer initial costs, but potential higher costs in the long run as the technology ages and requires more maintenance.
Familiarity & Expertise
The widespread use and understanding of IPv4 might lead to reduced costs in terms of training and expertise.
Existing IT teams are often more familiar with IPv4, reducing the need for external consultants or training programs.
Compatibility as a cost factor
Using IPv4 proxies to access IPv6-only websites causes compatibility issues. This means the loss of money spent on proxies and failure of the operation. So, when dealing with IPV6 only websites you should not use IP4 proxies.
Our verdict: IPV6 is better than IPV4 in the cost comparison.
Why? As the available IPv4 addresses continue to dwindle, the costs associated with obtaining and managing these addresses may grow disproportionately.
IPv6 also offers better features, such as enhanced security and improved performance, which could eventually prove to be cost-effective in the long run.
Comparing Compatibility and Proxy Use Cases
When selecting a proxy for your business, one essential factor to consider is the compatibility of the proxy with your existing systems and targeted websites or applications.
Both IPv4 and IPv6 proxies have their own compatibility considerations with different target websites and this affects their use cases.
IPv4 Proxies Compatibility
Due to the extensive period that IPv4 has been in operation, it offers widespread support and compatibility.
Most digital infrastructure is built around IPv4 addressing, which includes a vast majority of websites and applications. For a business, this means that using an IPv4 proxy is likely to offer seamless integration in most scenarios.
Main IPV4 use cases
IPv4 proxies are particularly useful in use cases where legacy systems or older hardware and software are in place, as they may not support IPv6.
IPv6 Proxies Compatibility
On the contrary, while IPv6 marks the future of internet protocols, it isn’t as widely adopted yet. As a result, the pool of available resources compatible with IPv6 is comparatively limited.
This is not going to stand though. Rapidly and efficiently, IPV6 is being implemented and is getting compatible with newer systems.
Examples of IPV6-Compatible websites include: Google SERPs and Social networks like: Facebook, Instagram, Linkedin, and Twitter.
Main IPV6 use cases
- Using social networks for data collection, scraping and monitoring brand mentions.
- Tracking website rankings on search engines like Google SERPs, ensuring accurate and diverse data collection.
Ipv6 vs Ipv4 Proxies: Security Comparison
Security is a critical factor to consider when choosing between IPv6 and IPv4 proxies for your business. Let’s explore the differences between the two in terms of security and how they can impact your operations.
IPv6 Proxy Security
Beginning with IPv6, the protocol introduces several enhanced security features not native to IPV4. This includes:
- Built-in IPsec: IPsec, or internet protocol security, is built-in to IPv6, whereas it is optional and must be manually configured in IPv4. This embedded IPsec in IPv6 assures proxy users of an additional layer of encrypted communication.
- Address Space: Given IPv6’s vast address range, automated attacks, such as IP sweeps, become significantly more complex. For businesses deploying proxies, this means potential attackers face a more daunting task identifying and targeting specific IPv6 proxy addresses.
IPv4 Proxy Security
Though IPv4 lacks the built-in security features seen in IPv6, it is not without its own security assets and advantages.
- Maturity: IPv4 has been around for more than three decades, and consequently there exist a wide array of tools and management practices developed over many years to secure the system.
- Optional IPsec: While IPsec needs manual configuration in IPv4, it is still flexible and not all traffic necessarily needs it.

Before You Choose The Proxy Type
When deciding between IPv4 and IPv6 proxies, businesses should think of these 3 key considerations to make an informed decision:
Auditing Targeted Sites
- Review what protocols your most accessed sites and services use. For example, if you frequently need to access IPv6 only sites like Facebook or Google, IPv6 proxies would provide better compatibility.
- Lay out a detailed cost-benefit analysis. This should incorporate potential infrastructure upgrades, the recurring costs of IP addresses, and any associated maintenance. Remember, with the vast reservoir of IPv6 addresses, you’re likely positioning your business for cost efficiency with them.
Listing Use Cases
- Clearly outline what you primarily need the proxies for. If it’s web scraping, which protocol offers swifter data extraction? If it’s ad verification, which ensures more accurate results? Sometimes, the nature of the task can hint at the optimal protocol.
