Choosing the wrong proxy type can quietly wreck your campaigns. If you’re managing automations, running multiple accounts, or scraping at scale, the IPv4 vs IPv6 debate isn’t just technical, it’s tactical.

Both protocols route traffic across the internet, but the differences between them impact everything from platform compatibility to ban rates and scalability.

In this guide, we’ll talk about:

  • The core differences between IPv4 vs IPv6
  • The real-world pros and cons of each for proxy use
  • Which protocol works better for tasks like ad verification, botting, account farming, or geo-based scraping

By the end, you’ll know which proxy type gives you the edge, and where mixing them up could cost you.

What are IPv4 and IPv6?

Here’s the backstory: The internet grew so fast that the original IP system ran out of room.

IPv4 (Internet Protocol Version 4) has been around since the early days of the Internet. It uses 32-bit addresses, which gives us about 4.3 billion unique IPs. Back in the 80s, that seemed like more than enough.

But the explosion of devices and users changed the game.

IPv6, launched to replace IPv4, uses 128-bit addresses, offering a jaw-dropping 340 undecillion IPs. It’s basically future-proof.

So why does this matter for proxies? Because each version behaves differently depending on the platform, the task, and your goals.

IPv4 Residential Proxies

IPv4 proxies are based on that older system. Because they’ve been around longer, most websites and apps were built to recognize and accept them.

  • High compatibility: Works with 99% of platforms, such as Amazon, PayPal, Instagram, etc.
  • Realistic footprint: Looks like real users, especially when tied to residential IPs.
  • Scarcity = higher cost: Because we’re running out of IPv4 addresses, IPv4 proxies tend to be more expensive.

IPv6 Residential Proxies

IPv6 proxies are newer, but not as widely supported. However, they come with some major perks.

  • Cheap and scalable: Massive pool of available IPs = low cost per IP.
  • Perfect for scraping: You get more IPs to rotate through and avoid bans.
  • Still not universal: Some platforms don’t support IPv6 yet, so compatibility matters.

IPv4 vs IPv6: Key Differences

So what actually sets IPv4 and IPv6 apart, besides their IP counts?

1. Type of Addresses

  • IPv4 uses dotted decimal format (e.g., 192.168.1.1).
  • IPv6 uses hexadecimal separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

2. Packet Size

IPv6 supports larger payloads, which can be useful in high-bandwidth tasks like video streaming or massive scraping operations.

3. Number of Header Fields

  • IPv4 has 12 header fields.
  • IPv6 has only 8, hence it’s simpler and more efficient.

4. Optional Fields

IPv6 does away with many of the optional fields found in IPv4. That reduces complexity, especially when managing traffic in scale-heavy setups.

5. Configuration

IPv4 requires manual configuration or DHCP. IPv6 offers stateless address auto-configuration (SLAAC), meaning devices configure themselves.

6. Security

IPv6 was designed with IPsec encryption built in. IPv4 can support encryption too, but it’s bolted on manually.

Still, in real-world proxy usage, your encryption depends more on your browser, app, or automation script than the protocol.

7. Compatibility

IPv4 wins hands down. Virtually every website, app, ISP, and device supports IPv4, because it’s been the default internet protocol for over 40 years. IPv6, while more modern and scalable, still suffers from partial adoption across the web.

If you’re dealing with old-school financial platforms or payment gateways, stick with IPv4.

IPv4 vs IPv6 Comparison Table

Here’s a little comparison table summarizing all the features and characteristics we have discussed above in the blog.

Feature IPv4 IPv6
Address Length 32-bit (e.g., 192.168.1.1) 128-bit (e.g., 2001:0db8:85a3::8a2e:0370:7334)
Total IPs Available ~4.3 billion ~340 undecillion
Header Complexity More complex (12 fields) Simpler (8 fields)
Configuration Manual or DHCP Automatic (SLAAC) and manual
Security Optional (IPsec add-on) Built-in IPsec support

Address Notation Dotted decimal (e.g., 192.0.2.1) Hexadecimal with colons (e.g., 2001:db8::1)
Adoption Rate (as of now) ~100% support across all major systems Growing but still not universal
Example Platforms That Prefer It PayPal, Amazon, Instagram, Meta Ads Google, YouTube, modern APIs with full IPv6 support

Pros and Cons of IPv4 vs IPv6

Let’s break it down simply.

IPv4 Pros

  • Universally supported
  • Trusted by most sites
  • Strong track record

IPv4 Cons

  • Expensive
  • Limited supply
  • More likely to be recycled or reused (especially if from poor providers)

IPv6 Pros

  • Huge pool = cheap and available
  • Less competition per IP
  • Fast and efficient for bulk tasks

IPv6 Cons

  • Not compatible with all platforms
  • Detection risk if used on unsupported sites

IPv4 vs IPv6: Which One to Use

It depends on what you’re doing. Choosing between IPv4 and IPv6 proxies can directly impact your success rate, cost-efficiency, and stability.

Here’s how to break it down based on what you’re actually trying to do.

IPv4 Proxies: Ideal Use Cases

If you’re targeting platforms that are picky about trust, reputation, and IP consistency, IPv4 is your safest bet.

These proxies are the standard for compatibility, especially when dealing with older platforms, payment gateways, or anything with strict anti-fraud systems.

IPv4 residential proxies are your go-to.

Examples:

  • PayPal multi-accounting
  • TikTok and Meta ad accounts
  • Sneaker copping on legacy platforms
  • Amazon buyer/seller accounts
  • Stripe & financial automations

IPv6 Proxies: Ideal Use Cases

When scale and speed matter more than universal access, IPv6 proxies step in as the go-to solution.

They’re perfect for high-volume, low-risk operations where you need thousands of fresh IPs without burning your budget.

IPv6 proxies are unbeatable.

Examples:

  • Scraping search engines
  • Simulating ad clicks or visits
  • Load testing
  • Web data aggregation

What to Consider When Choosing Between the Two

Here’s what really matters:

  • Platform compatibility: Always check if your target site supports IPv6.
  • Trust level required: Use IPv4 for sensitive logins or transactions.
  • Scale & budget: IPv6 is more affordable for big jobs.
  • IP quality: Go with providers that screen their IP pools.

Frequently Asked Questions (FAQs)

What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses and supports around 4.3 billion unique IPs, while IPv6 uses 128-bit addresses, offering over 340 undecillion. IPv6 also includes built-in encryption, auto-configuration, and is more scalable, while IPv4 remains more widely supported across the web.
Is IPv6 faster than IPv4?
In most cases, the speed difference is negligible. However, IPv6 can be slightly faster due to simpler routing and fewer NAT (Network Address Translation) hops. That said, real-world performance often depends on your ISP and the target server’s configuration.
Is IPv4 faster than IPv6?
Only when the network or website you’re accessing doesn’t fully support IPv6. Since IPv4 is universally compatible, it may offer faster response times in certain setups where IPv6 fallback is required.
Is IPv6 faster than IPv4 for gaming?
Not necessarily. For online gaming, latency is more influenced by server distance and routing than the IP version. Unless the game servers and your ISP both fully support IPv6, you likely won’t notice a speed difference.
Is IPv6 better than IPv4?
It depends on the use case. IPv6 offers a larger IP pool, better efficiency, and built-in security. But IPv4 wins in compatibility and is more stable for legacy platforms. One isn’t objectively “better” — it’s about what fits your specific workflow.
How to change IPv4 to IPv6?
Most modern operating systems and routers support IPv6 automatically. To switch, enable IPv6 in your network settings, ensure your ISP supports it, and update DNS settings if needed. Proxy users should select an IPv6-supported proxy provider.
How to convert IPv6 to IPv4?
You can’t directly convert one into the other — they’re fundamentally different protocols. However, dual-stack setups and proxy services like NodeMaven allow you to run both IPv4 and IPv6 simultaneously based on compatibility needs.
How many more IP addresses in IPv6 than IPv4?
IPv6 supports 2¹²⁸ addresses — that’s about 340 undecillion. IPv4 only supports around 4.3 billion. That’s roughly 79 octillion times more IPs in IPv6, making it ideal for the future of internet-connected devices.
