IPv4 vs. IPv6 Proxies – Differences for Online Retail & More

For online retail, IPv4 proxies are the safer choice at checkout, and IPv6 proxies only make sense on stores you have confirmed accept them. IPv4 works with nearly every storefront and anti-bot service, while IPv6 is far cheaper but only connects to sites that publish an IPv6 (AAAA) record. This breakdown of IPv4 vs IPv6 proxies covers compatibility, price, ban risk and speed for anyone running NikeShoeBot tasks on Shopify, Nike, Amazon or Supreme drops.

Both types hide your personal home IP address so you can run multiple tasks safely. However, they work very differently in practice, and the one you pick directly affects whether you check out or get blocked.

What Are IPv4 and IPv6?

An IP address is the unique digital address every device on the internet uses, from your home computer to a retailer’s massive server, so computers can find each other and send data back and forth.

• IPv4 (Internet Protocol version 4): The original format of the internet. An IPv4 address looks like four numbers separated by dots (for example, 192.168.1.1) and is 32 bits long, which gives 2^32 = 4,294,967,296 possible addresses, or about 4 billion according to APNIC. Almost every website and security system was built around it.
• IPv6 (Internet Protocol version 6): The newer version, created because the traditional pool ran out. According to APNIC’s IPv4 address report, IANA exhausted its free pool on 3 February 2011, and ARIN’s ran out on 24 September 2015. IPv6 uses 128-bit addresses, as defined in RFC 8200, so the supply is almost endless.

When you plug a proxy into your bot, you are renting an IP address from a provider, so websites see that address instead of your real home one. Because the two versions are built on different technologies, they behave very differently when you are trying to cop hyped items.

IPv4 vs IPv6 Proxies: Website & Retailer Compatibility

The single most important rule in botting is that your proxy must be able to talk to the store you are targeting.

• IPv4 proxies: The universal standard. Virtually every online store, payment system, and anti-bot security service (like Cloudflare, DataDome, and Akamai) fully supports IPv4 connections.
• IPv6 proxies: They only connect to stores that have set up IPv6. About 50% of the top 1,000 websites support it, according to Internet Society Pulse, so for any single retailer it is close to a coin flip until you check. Support is also often partial: a 2025 arXiv study found only 12.5% of the top 100,000 websites were fully functional over IPv6, because many pages still lean on IPv4-only resources.

Real-World Example: Imagine setting up 50 tasks with IPv6 proxies to target a hyped drop on a sneaker store. If that store only accepts IPv4 connections, every single task will fail to load the page. IPv4 proxies take that risk off the table.

Can I Use IPv6 Proxies in NikeShoeBot?

Yes, modern bots like NikeShoeBot let you enter IPv6 proxies, but whether your tasks succeed depends on the store you are targeting. We have not verified IPv6 support for each retailer and it can change, so check the store first using the method below. For checkout, IPv4 ISP or residential proxies remain the safer choice.

How Can I Tell if a Store Supports IPv6?

Check the domain’s DNS records from your command terminal (Command Prompt on Windows or Terminal on Mac). If the lookup returns an “AAAA” record, the website supports IPv6. If it only returns an “A” record, the site only supports IPv4.

nslookup -type=AAAA example.com

An AAAA record only covers the domain you looked up, so test the checkout, payment and anti-bot domains too, since a store can be reachable over IPv6 while parts of its checkout are not.

Price and Supply: Why Is IPv6 So Much Cheaper Than IPv4?

The price gap between the two types comes down to basic supply and demand.

• IPv4 proxies: The global supply of IPv4 addresses is completely full, meaning no new ones are being created. Because they are rare and in high demand, IPv4 proxies (especially residential and ISP) cost more money.
• IPv6 proxies: IPv6 was created to solve the shortage. A single /64 block holds 2^64 = 18,446,744,073,709,551,616 addresses, which is 2^32 = 4,294,967,296 times the entire IPv4 space (2^64 / 2^32 = 2^32). Because they are so easy for providers to create, IPv6 proxies are extremely cheap.

Real-World Example: According to RapidSeedbox’s comparison, $48 a month buys 48 IPv4 proxies or 1,000 IPv6 proxies, which is $1.00 against $0.05 per address, or 20 times cheaper ($1.00 / $0.05 = 20).

Prices vary by provider, but the gap holds. Meanwhile, a good pool of IPv4 ISP or residential proxies costs more because providers pay high prices to rent real home internet addresses. Cheap IPv6 proxies are still a waste of money if the site you want to bot doesn’t accept them.

Anti-Bot Protection and Ban Risks

Modern anti-bot software is designed to catch and block bots before they can check out, and how it views your proxies depends on whether they are IPv4 or IPv6.

• IPv4 blocking: Anti-bot systems usually block IPv4 addresses one by one. Because these IPs belong to real home internet users, security systems are careful not to block large groups of them by mistake, as that would lock out real customers.
• IPv6 blocking: Because IPv6 proxies are so cheap, people often use them to fire off thousands of fast requests, and defenders know it. Rate limiters commonly group IPv6 clients by their /64 prefix, as the httprate documentation describes, so one suspicious address can get a whole block treated as a single client.

Real-World Example: If you run multiple Amazon tasks on IPv6 proxies from the same provider, a security system might catch one task and flag the whole block, taking your other tasks down in one move. With IPv4 residential proxies, each task looks like a different person shopping from a different home in a different city, which makes it much harder for anti-bot systems to group and block them.

Speed and Performance

Speed depends on the quality of your provider and the route more than on the protocol itself.

• IPv4: High-quality IPv4 ISP proxies deliver very fast checkout speeds straight from data centers, while residential IPv4 proxies are slightly slower but much safer against bans.
• IPv6: IPv6 can be efficient because it needs fewer address translation steps. However, that extra speed only matters on the retail sites that fully support IPv6.

Real-World Example: If you are monitoring price changes or checking stock across thousands of product pages on a site that supports IPv6, IPv6 proxies let you run many fast tasks at a low cost. For actual drop days on limited items, though, the proven reliability of IPv4 is worth far more than the raw speed of IPv6.

Summary Verdict: Which Should You Use?

IPv4 residential and ISP proxies are the right pick for checkout, and IPv6 proxies are a budget tool for monitoring and scraping.

Use IPv4 proxies (residential & ISP) for:

• Copping hyped items on Nike SNKRS, Supreme, Shopify, PlayStation, and Amazon.
• Lower ban risk against strict anti-bot systems.
• Reliable connections on stores that only accept IPv4.

Use IPv6 proxies for:

• High-volume price and stock monitoring on confirmed IPv6-compatible sites.
• Budget-friendly scraping tasks where site compatibility is verified in advance.

What Is the Safest Proxy Setup for High-Heat Drops?

For high-heat drops, combine fast IPv4 ISP proxies (for initial connection speed) with IPv4 residential proxies (for high trust and ban protection). That pairing gives you the best chance of securing items safely, especially alongside clean profiles and virtual credit cards you trust.
