Proxy for IPv4

In the world of networking technologies, there is a certain nuance. On one hand, we’ve been told for over a decade that IPv4 addresses have officially run out. On the other hand, any professional in SMM, digital marketing, or data analytics will tell you that to get the job done, they need to buy IPv4 proxies, as this guarantees maximum compatibility.

Why does this happen? Why does this "classic" protocol remain indispensable for 99% of work tasks, and why does the attempt to save money by using IPv6 often create access difficulties?

This article is a technical overview. We will analyze why IPv4 proxies are an industry standard, not a relic of the past, and how to choose them correctly for your specific tasks.

Part 1. Two Protocols: Why is IPv4 "trusted" while IPv6 is not?

To understand the essence, we need to recall the basics.

• IPv4 (Internet Protocol v4): This is the classic IP address format we all know: 93.184.216.34. It is 32-bit, which gives us "only" 4.3 billion unique addresses. These ran out around 2012.
• IPv6 (Internet Protocol v6): This is the "new" 128-bit format: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The number of these addresses is... almost infinite. There are enough to assign an IP address to every device on the planet.

It would seem that this is the solution! However, in practice, the security algorithms of major platforms (Google, Facebook, Instagram) have built their logic on the principle of reputation and usage history.

According to Google data as of October 2025, the share of IPv6 traffic globally is about 44.5%. In the USA, it exceeds 50%, in India—over 77% (according to APNIC), and in countries like France and Germany—up to 60%. However, in Russia and the CIS, IPv6 adoption remains low—around 20-30% (based on regional data from APNIC and the Internet Society), due to infrastructure specifics. This confirms why IPv4 dominates in local tasks and why buying IPv4 proxies remains a necessity for stable operation.

Why security systems are cautious with IPv6:

1. Low entry barrier: IPv6 addresses are extremely accessible. Due to the mass generation of addresses, they often lack a fixed long-term "history" associated with a specific user. A new IPv6 address often has no digital reputation.
2. Infrastructure differences: The vast majority of real home users (via Wi-Fi) and mobile users (via 4G/5G) operate through IPv4 proxies or NAT technologies that group devices together. For web resources, an entry from an "isolated" IPv6 can look like automated technical traffic, triggering additional checks.

Why platforms trust IPv4:

1. Resource value: IPv4 addresses are a limited resource that is more strictly administered by providers.
2. Accumulated reputation: Every IPv4 address has a history (ASN, provider, geography). A high-quality IPv4 proxy with the reputation of a real provider is a reliable asset that ensures unhindered access to services.

Conclusion: In today's internet, IPv4 proxies are your digital pass, confirming the legitimacy of your connection. Meanwhile, IPv6 can still face compatibility limitations on a number of resources.

Part 2. When are IPv4 proxies indispensable?

The answer is simple: whenever connection stability and the absence of redundant checks are important. Any attempt to buy IPv4 proxies is an investment in reliability.

• SMM (Facebook, Instagram, TikTok): Session stability is vital for professional business account management. Using high-quality IPv4 prevents sudden connection drops and re-authorization requests that often occur when switching IPv6 subnets.
• Data processing (Google, marketplaces): To analyze search results or prices, a stable connection is required. You need residential rotating IPv4 proxies, which allow you to collect public data anonymously without overloading target servers with requests from a single IP.
• Ad management: Running large-scale advertising campaigns requires a clean network history. Ad network algorithms are sensitive to connection quality. Only mobile or residential IPv4 proxies will provide your ad accounts with long and stable performance.

Part 3. How to choose and buy IPv4 proxies: A complete guide

So, we've established that we need an IPv4 proxy. But they come in different types. Let's look at what to consider when purchasing.

1. Protocol type: SOCKS5 or HTTP(S)?

For 99% of professional tasks, the answer is SOCKS5.

• HTTP(S) proxies are designed primarily for web surfing.
• IPv4 SOCKS5 proxies are a universal protocol. They operate at a lower level and can transmit traffic for any application: messengers, email clients, analytical software, or specialized browsers.

If you see an opportunity to buy SOCKS5 IPv4 proxies, always choose it. This guarantees maximum compatibility with your software.

2. Address type: Static, Rotating, Residential, Mobile

• Static IPv4 (Server/Datacenter): You get one IP address for the entire rental period.
• Pros: Often these are affordable proxies. They are fast and have a stable channel.
• Cons: Some websites can identify them as belonging to hosting providers.
• Verdict: Suitable for standard tasks and working with resources without strict geo-filters.
• Rotating IPv4 proxies:
• How they work: The external IP address changes with every request or on a timer. Rotation provides high anonymity.
• Verdict: Ideal for analytics (Data Mining). If you decide to buy rotating IPv4 proxies, you gain access to a pool of addresses for large-scale data collection.
• Residential and Mobile IPv4:
• How they work: These are IP addresses assigned to home ISPs or mobile operators. This is the quality standard.
• Verdict: The highest level of trust from web resources. Indispensable for marketing and advertising.

3. Geography: Why choosing the right GEO is a necessity, not a whim

This point is critically important. It concerns how website security systems react to data inconsistency (incongruence).

What is the real problem?

Platforms analyze not just the login/password, but also the connection context.

• Scenario 1 (Regular user): IP from Netherlands + Profile registered in Netherlands + Matching system language.
• System reaction: Standard login. Access granted.
• Scenario 2 (Marketer with the wrong proxy): IP from a datacenter in Netherlands + Profile working in the Moscow region + Specialized software + Active work.
• System reaction: Suspicious activity. Moscow profile + IP from another country = High probability of unauthorized access.

What does this lead to?

In Scenario 2, the platform initiates a security check. Access may be temporarily restricted until the owner's identity is confirmed.

For a specialist managing multiple projects, such checks significantly slow down the workflow.

The Solution — Geo-matching:

This is why, if you are working with local services (VKontakte, Yandex, Avito), it is important to buy Russia IPv4 proxies. This ensures logical data consistency.

Using such proxies makes your activity legitimate. This minimizes the risk of captchas or additional checks and ensures uninterrupted operation.

4. Cost and Quality

• Price: Quality IPv4 proxies require maintenance. If you see an offer to "buy IPv4 proxies too cheaply," be careful. These are often public addresses with low speeds and poor reputations (sharing "neighborhoods" with other users).
• Term: For short tests or one-off data collection tasks, daily IPv4 proxies are a great fit. This optimizes your budget.

Before you buy an IPv4 proxy, check its quality:

• IP Reputation: Use checkers to verify geo and provider.
• Speed and Stability: Low ping and high uptime are important for comfortable work.
• Anonymity: Ensure the proxy correctly transmits headers and hides your real address.
• Compatibility: Test the connection with your work software. Clean IPs guarantee no access issues with target resources.

Conclusion: IPv4 is a Reliable Standard

As long as internet marketing and e-commerce are built on interactions with platforms that have high security requirements, IPv4 proxies will remain the primary working tool.

The transition to IPv6 for commercial tasks takes time. Until then, any professional who values the stability of their projects will buy and use IPv4 proxies as a proven solution.
