Cosa sono i proxy IPv4 e IPv6 nel 2023 e come aiutano a svolgere le attività online.

Secondo IP2location, gli Stati Uniti d'America hanno un totale di 1.535.324.160 indirizzi IP assegnati. Poiché gli utenti di Internet stanno crescendo ad un ritmo esponenziale, diventa necessario proporre versioni migliorate degli indirizzi di protocollo Internet per soddisfare i requisiti. Questo articolo illustra le versioni di indirizzi IP più utilizzate, IPv4 e IPv6, e le loro caratteristiche.

Che cos'è un indirizzo IP?

Take the example of someone who wants to send a courier to your place. The main thing they need is your name and address. Once they acquire your address, they can send couriers to your home. Taking the same scenario, you want to send data online—so how do you do that? Same thing—you need to acquire the host’s address (target).

IPv4 and IPv6 are internet protocols, or IP addresses, that enable internetworking, which means they help form the internet. But there are two internet protocol versions. Which one is better? The direct answer is IPv6, but we have to compare IPv4 and IPv6 to explain why IPv6 is considered better. In the upcoming sections, we will look at IPv4 and IPv6, their pros and cons, what IPv4 and IPv6 proxies are, and the best IPv6 proxies in 2023.

IPv4 e IPv6 - Cosa sono?

As mentioned above, IP (Internet Protocol) versions 4 and 6 are mainly used for communication, routing, and addressing data packets in electronic devices, such as desktops, tablets, mobiles, and laptops, across interconnected networks. The important thing to note is that each public IP address assigned to a device is unique and in numerical format. For example, an IP address might look like 198.111.110.00.

IPv4 uses a 32-bit format, i.e. 2^32, and provides around four billion unique addresses. Even though that sounds like a lot, it can lead to exhaustion due to the growing number of internet-connected users and devices. To solve that problem, a new internet protocol system was introduced: IPv6.

IPv6 is an upgraded version of IPv4 and uses 128-bit addressing, i.e. 2^128. This allows for an extremely large number of unique addresses—enough to support the internet for generations to come. IPv6 greatly reduces the risk of running out of IP addresses.

Pros and Cons of IPv4

Pro:

Consumes Less Memory — IPv4 headers are smaller (32-bit), which means less packet overhead. However, memory use depends on the implementation, not just the protocol.
Seamless Support — Since IPv4 has been around longer, it is more widely supported. Most legacy systems, devices, and networks are built around IPv4.
Security Support — IPv4 supports security features such as IPsec, but it's optional and not built into the core protocol like in IPv6.

Contro:

Inferior Routing — IPv4 routing can be more complex due to address fragmentation and the need for NAT (Network Address Translation). IPv6 offers more efficient routing with its larger address space and simpler headers.
Higher Cost — IPv4 addresses are limited and now considered scarce, which increases cost. Also, managing NAT and overlapping private networks adds complexity.
Limitation in Number of Addresses — IPv4 supports approximately 4.3 billion unique addresses, which is not enough for the modern internet scale.

Pros and Cons of IPv6

Pro:

Potential for Higher Speed — IPv6 can improve performance in some cases due to simplified packet headers and the elimination of NAT. However, IPv6 is not inherently faster than IPv4 in all scenarios.
Massively Increased Number of IP Addresses — IPv6 has 2^128 addresses, which is not four times, but 340 undecillion times more than IPv4. This virtually eliminates the risk of address exhaustion.
Improved Routing — IPv6 allows for more efficient and hierarchical routing, making it better suited for modern internet infrastructure.
High-Level Security — IPv6 has built-in support for IPsec, enabling features like data integrity, authentication, and protection against replay attacks. However, these features are not always enabled by default.

Contro:

Complex Integration Process — Because many systems still use IPv4, transitioning to IPv6 takes time and planning. Dual-stack configurations (running IPv4 and IPv6 together) are often needed.
Difficulty in Communication — IPv4 and IPv6 are not directly compatible. To allow communication between them, special translation or tunneling methods must be used. Dual-stack or NAT64/DNS64 are common approaches.

Cosa sono i proxy IPv4 e IPv6?

Proxies are intermediaries between you and the target servers. They mask your original IP address with their own IP address, so the target server sees the proxy’s IP instead of yours. This helps with anonymity, bypassing restrictions, and balancing traffic loads.

A proxy that uses IPv4 addresses is known as an IPv4 proxy, and a proxy that uses IPv6 addresses is known as an IPv6 proxy.

Esempio:

An IPv4 address is a 32-bit numeric address, such as
- A proxy using this format is an IPv4 proxy.
An IPv6 address is a 128-bit alphanumeric address, such as
- If converted to binary, this results in 128 bits (or 16 bytes).
- IPv6 addresses use hexadecimal digits and are separated by colons, making them visually distinct from IPv4.

Another simple way to distinguish them:

IPv4 addresses are purely numeric and use dots (
IPv6 addresses include both numbers and letters (a–f) and use colons (

IPv6 proxy servers are often used in modern networks and can be more efficient when a large number of IPs is needed. However, they are not specifically “best suited for mobile devices” — both IPv4 and IPv6 can be used on mobile networks, depending on the carrier and device support.

ScraperAI:

ScraperAI is one of the top online proxy providers for IPv6 proxies. With access to over 20 million IPv6 addresses, you can feel confident that you’ll have a steady supply of proxies whenever you're working. One important thing to note is that they do not offer dedicated or datacenter proxies. All proxies are mixed—meaning they come from various ISPs (Internet Service Providers), often including residential and mobile sources—and you can switch proxies at any time. You can also add parameters like “&premium=true” to filter for higher-quality residential proxies. Additional features include geo-targeting and support for JS (JavaScript) rendering, making it easier to scrape websites with dynamic content.

ProxyScrape:

ProxyScrape is one of the best proxy providers for IPv4 addresses online. ProxyScrape provides three main proxy services: residential, dedicated, and premium proxies. Let’s briefly learn about the three services:

HTTP proxies are generally a little faster than SOCKS proxies because they handle only HTTP(S) traffic and consume fewer server resources. With a total network capacity of over 20 Gbps, this proxy server type should suit the majority of high-speed use cases.

Residential Proxies – Residential proxies are less likely to be blocked because they use real IP addresses assigned by Internet Service Providers (ISPs). With a median latency around 1000ms, residential proxies are best for demanding tasks like web scraping or automation. These are rotating proxies, meaning your IP address changes with each new connection to the ProxyScrape network. Currently, residential proxies support HTTP(s) protocol and username/password authentication. ProxyScrape offers access to over 7 million IPs in its residential proxy network.

Premium Proxies – Premium proxies are shared datacenter proxies. The only difference from dedicated proxies is that multiple users share the same IP. With bandwidth support of up to 50,000 HTTP requests per second, and support for SOCKS4/5 and HTTP(s), they are great for high-internet-traffic activities like price monitoring, SEO tools, or botting. These proxies offer fast and stable performance for general-purpose automation.

Dedicated Proxies – Dedicated proxies are private datacenter proxies with unlimited bandwidth, used only by you. This means more control, better consistency, and lower risk of IP bans compared to shared networks. With speeds of up to 1 Gbps, they are perfect for high-speed tasks such as gaming, sneaker botting, or account management. The average response time depends on the protocol:

HTTP: 375 ms
SOCKS4/5: 575ms
Tempo di attività: 99,99%.

ProxyScrape provides a user-friendly dashboard to manage your proxies and monitor usage. With 24/7 technical support, most issues are resolved within 24 hours.

NOTE: As mentioned above, IPv4 proxies are still the most commonly used type in organizations and for personal use. Most modern devices—including desktops, laptops, and mobile phones—support IPv4. It’s always a good idea to check device compatibility before setting up proxies.

Domande frequenti

1. Which is better: IPv4 or IPv6 proxy? IPv4 is the older version and is supported by nearly all devices and websites. IPv6, on the other hand, provides a much larger address pool and includes native support for certain security features. If you need broad compatibility, go with IPv4. If you prioritize scalability or access to a high number of clean IPs, IPv6 is a great choice.

2. Should I disable IPv6 on my local system? Not recommended. Some applications may not behave correctly when IPv6 is fully disabled. Instead of turning it off completely, it's better to prioritize IPv4 in your network settings if needed. This allows both protocols to work properly without causing connectivity issues.

3. Which is better for gaming: IPv4 or IPv6 proxies? IPv6 has the potential to reduce latency in some networks due to more direct routing and no NAT. However, performance depends more on the quality of the proxy server and network setup. In many cases, both IPv4 and IPv6 can work well for gaming and streaming, as long as the connection is stable and fast.

Conclusione:

In this article, we have learned more about IPv4 and IPv6 proxy addresses and how they are essential to online communication between devices. So, which is better—IPv4 or IPv6? IPv6 is a better long-term choice, as it is the next-generation version of IPv4, offering more IP addresses and built-in support for security features. However, the main drawback is that IPv6 is still not fully supported by all networks, devices, or websites. This is where the preference starts to vary. The simple answer is: if your device and target services support IPv6, then IPv6 is a strong choice. Otherwise, IPv4 remains the more widely compatible option for now.
