When you search for proxies for scraping, SEO, or anonymous surfing, you’ve probably seen queries like “buy IPv6 proxy” or “IPv6 proxy online”. IPv6 seems modern and promising, but why are these proxies so rarely used? Let’s figure out what IPv6 proxies are, why they don’t always meet expectations, and which alternatives are better.

What are IPv6 proxies and why do they attract attention?

IPv6 is the new version of the Internet Protocol, designed to replace IPv4. It offers a huge number of addresses (340 undecillion, to be exact), which makes it appealing to those looking for IPv6 proxies. For example, providers offer rotating IPv6 proxies where you can get thousands of addresses at a low cost. This sounds like a perfect option for large-scale scraping or bypassing blocks.

Why do people search for “IPv6 proxy online”? First, IPv6 proxies are cheaper because addresses are easier to obtain. Second, advertising often promises high speed and scalability. But reality is not so bright.

Limitations of IPv6 proxies: why don’t they always work?

Compatibility with websites and services

Most websites and platforms still run on IPv4. For example, if you want to scrape a large marketplace or social network, chances are they don’t support IPv6. This means your request via an IPv6 proxy simply won’t go through. An IPv6 proxy checker often shows the server as available, but the target site “doesn’t see” it.

Blocking of IPv6 addresses

Many platforms, especially those fighting scraping or spam, block IPv6 addresses by default. For example, if you use rotating IPv6 proxies for data collection, you may quickly face bans because sites easily recognize IPv6 address ranges.

Lower support in tools

Many SEO, scraping, or automation tools (e.g., older browsers or software) don’t support IPv6. Even if you find a “web IPv6 proxy,” integration can be complicated. For instance, setting up proxies in a Python script often requires extra libraries if it’s IPv6.

Why IPv4 proxies remain the better choice

Comparing IPv6 vs. IPv4 shows that IPv4 proxies still win in versatility. Here’s why:

  • Broad compatibility: Almost all sites, services, and tools work with IPv4.

  • Fewer blocks: IPv4 addresses are harder to track and block, especially private or rotating ones.

  • Ease of use: Setting up IPv4 proxies usually requires no extra steps.

For example, buying IPv4 proxies for Google scraping ensures stable connections and fewer bans. In contrast, IPv6 proxies may “break” on the first request due to incompatibility.

What alternatives to choose instead of IPv6 proxies?

If IPv6 proxies are problematic, what should you choose? Here are better options:

  • Rotating IPv4 proxies – The gold standard for anonymity and frequent IP changes.

  • Mobile proxies – Use mobile operators’ IPs, rarely blocked, ideal for Instagram or TikTok scraping.

  • Residential proxies – Real user IPs (home Wi-Fi), highly anonymous and reliable, best for advanced tasks.

When can IPv6 proxies still be useful?

Despite limitations, they can help in:

  • Testing new IPv6-ready services.

  • Large-scale scraping on a low budget.

  • Regional tasks (e.g., some Asian platforms already support IPv6).

Always run an IPv6 proxy check before buying to confirm compatibility.

Tips for choosing proxies

  • Check compatibility before purchase.

  • Try rotating IPv4 proxies — they cover 99% of cases.

  • Test providers with trial access.

  • Consider your budget — IPv6 may be cheap, but IPv4/mobile is more effective.

Conclusion

Searches like “buy IPv6 proxy” or “proxy IPv6” show demand for cheap, modern solutions. But in reality, IPv6 proxies still lose in compatibility and versatility. They are useful for niche cases, but for most tasks, rotating IPv4 or mobile proxies are better. Always test proxies with providers like StableProxy before buying to ensure they meet your needs.
