IPv4 vs. IPv6 Proxies

Get an understanding on IPv4 and IPv6 proxies and help you determine the right proxy for your usecase.

IPv4 vs IPv6

IPv4 and IPv6 are the two primary versions of the Internet Protocol (IP) that are in use today. While IPv4 has been the dominant protocol for decades, IPv6 is becoming increasingly important due to the exhaustion of available IPv4 addresses.

When choosing between IPv4 and IPv6 proxies, it is essential to consider factors such as compatibility, address pool size, security, and performance.


What is IPv4?

IPv4 is the most widely used version of IP to date. It uses 32-bit addresses, which allows for a total of approximately 4.3 billion unique addresses. This has been in use since the early days of the internet and is the foundation of the modern internet.

IPv4 addresses are typically written in dotted-decimal notation, separating each octet by a period.
For example, an IPv4 address may look like this:


What are IPv4 Proxies?

IPv4 proxies are a type of proxy server that uses the IPv4 protocol, which is the most common protocol used on the internet today. IPv4 proxies can work with both IPv4 and IPv6 websites, but they may not be able to access websites that are IPv6-only. IPv4 proxies tend to be less expensive and easier to set up compared to IPv6 proxies. They are widely used for a variety of reasons, such as improving internet speed, hiding online identity, and accessing geo-restricted content.

Advantages of IPv4 proxies

Using an IPv4 proxy can be extremely beneficial. Some of the key benefits include:

Security: Proxy servers, including IPv4 proxies, add an additional layer of security by acting as a barrier between the user’s device and the internet, filtering out malicious content, detecting and blocking malware, and preventing unauthorized access to sensitive data.
Privacy: By hiding user IPs and location, IPv4 proxies offer anonymity across the internet, helping protect sensitive information and prevent tracking.
Network Control: Proxy servers allow for a higher level of control over local networks and websites by filtering out malicious content, detecting and blocking malware, and preventing unauthorized access to sensitive data.
Performance Optimization: IPv4 proxies can cache frequently accessed content, reduce bandwidth usage, and increase site speed. They also offer load balancing by pushing client requests to appropriate servers.
Global Reach: By connecting to an IPv4 proxy server located in a different country, users can access websites and online services that are otherwise unavailable in their location.

Disadvantages of IPv4 proxies

But, using an IPv4 proxy is not always benifical. In fact, here are some of its key drawbacks:

Performance Impact: IPv4 proxies can introduce latency and impact performance, especially if they are overloaded or misconfigured. Properly managing proxy server resources and optimizing configurations can help mitigate performance issues.
Security Risks: Improperly configured or compromised IPv4 proxies could potentially expose sensitive information, introduce vulnerabilities, or become targets for cyber attacks.
Single Point of Failure: IPv4 proxies may represent a single point of failure in the network architecture. Implementing redundancy, failover mechanisms, and backup proxy servers can help mitigate the risk of downtime and minimize service disruptions.
Privacy Concerns: Some IPv4 proxies may log user activity, including websites visited and data transmitted, compromising user privacy. It’s essential to understand and evaluate the privacy policies and logging practices of IPv4 proxy servers.
Compatibility Issues: Certain protocols, encryption methods, or authentication mechanisms may not be supported by IPv4 proxies, leading to connectivity issues or functionality limitations.


What is IPv6?

IPv6 uses 128-bit addresses, allowing for a vastly enlarged address space compared to IPv4’s 32-bit addresses.

IPv6 addresses are represented in hexadecimal format, separated by colons, and can be shortened using various techniques.

IPv6 supports:

  • Unicast addressing
  • Anycast addressing
  • Multicast addressing
  • Improved security
  • Simplified header structure

Its larger address space and enhanced capabilities make IPv6 a crucial part of the future of the internet.

What are IPv6 proxies?

IPv6 proxies are intermediary services that use IPv6 addresses to connect users to the internet. Unlike IPv4 proxies, IPv6 proxies offer a vast address space, enhanced security features, and improved performance.

Use cases where IPv6 proxies are particularly beneficial include large-scale web scraping, bypassing geo-restrictions, and accessing IPv6-only services. With IPv6’s vast address space, users can access a much larger pool of available IP addresses, reducing the risk of IP blocks and improving the success rate of web scraping operations.

Advantages of IPv6 proxies

There are several advantages of using IPv6 proxies. Some of they key benefits include:

Increased Address Space: IPv6 proxies can handle a much larger number of unique addresses than IPv4 proxies, making them more scalable and future-proof.
Improved Security: IPv6 proxies can provide better security features, such as mandatory implementation of IPsec (Internet Protocol Security) support, which helps protect against unauthorized access and data tampering.
Better Performance: IPv6 proxies can offer improved performance and faster data transfer rates due to the more efficient packet header format and improved routing mechanisms.
Simplified Network Configuration: IPv6 proxies can simplify network configuration and reduce the need for NAT (Network Address Translation) and other workarounds.
Future-Proofing: As the internet continues to transition to IPv6, using IPv6 proxies can help ensure that your network infrastructure is future-proof and ready for the next generation of internet protocols.

Disadvantages of IPv6 proxies

Despite the benefits, using IPv6 proxies are not beneficial all the time. In fact, some key drawbacks of using IPv6 proxies include:

Limited Compatibility: IPv6 proxies may not be compatible with all devices, networks, or applications that still rely on IPv4.
Higher Resource Requirements: IPv6 proxies may require more powerful hardware and resources to handle the increased address space and more complex packet headers.
Increased Complexity: IPv6 proxies can be more complex to configure and manage, especially for networks with existing IPv4 infrastructure.
Limited Availability: IPv6 proxies may not be as widely available as IPv4 proxies, and may require specialized providers or setup.
Higher Cost: IPv6 proxies may be more expensive to implement and maintain, especially for smaller networks or organizations.


IPv4 vs. IPv6 Proxies

One of the most significant differences between IPv4 and IPv6 proxies is the address space. IPv4 uses 32-bit addresses, which allows for approximately 4.3 billion unique addresses. In contrast, IPv6 uses 128-bit addresses, which allows for approximately 3.4 x 10^38 unique addresses. This vast address space in IPv6 provides significant scalability benefits, making it an ideal choice for large-scale web scraping and other data-intensive applications.

Here’s a table of the comparison between IPv4 and IPv6 proxies:
