A proxy subnet is a group of IP addresses that share the same network prefix.
For sneaker botting, this means 100 different proxy IPs don’t necessarily give you 100 completely separate network identities. If a big chunk comes from the same subnet, your proxy pool can be more concentrated than it looks.
That matters during sneaker releases because retailers can evaluate the IP behind a task alongside reputation, browser fingerprints, request patterns, and session behavior. Subnet diversity helps spread your network footprint, but it ain’t some magical ticket to a W.
What Is a Proxy Subnet?
A subnet is basically a smaller network inside a larger IP network. IP ranges are commonly represented using CIDR notation.
For example, AWS documents that a /24 IPv4 CIDR block contains 256 IP addresses. So addresses such as 192.0.2.10 and 192.0.2.200 can belong to the same /24 even though the individual IPs look different.
| PROXY EXAMPLE | /24 NETWORK | SAME SUBNET? |
|---|---|---|
192.0.2.10 | 192.0.2.0/24 | ✓Yes |
192.0.2.75 | 192.0.2.0/24 | ✓Yes |
192.0.2.200 | 192.0.2.0/24 | ✓Yes |
198.51.100.20 | 198.51.100.0/24 | ×No |
That distinction is worth knowing before buying a giant proxy pool. If proxies themselves are still fuzzy, our sneaker proxies guide covers how they fit into a bot setup.
Why Does Subnet Diversity Matter for Sneaker Bots?
Subnet diversity tells you whether your IP pool spans multiple network ranges instead of being heavily concentrated in one.
Say you have 100 proxies. If 80 sit inside one network range, that’s a very different pool from 100 addresses distributed across several unrelated ranges. The raw proxy count is identical, but the network diversity isn’t.
And retailers aren’t judging IPs in isolation. As we covered in how sneaker websites detect bots, modern anti-bot systems can combine network information with fingerprints, headers, request patterns, JavaScript results, and behavior.
So yeah, subnet diversity matters. It just isn’t the whole setup.
Does a Different Subnet Mean a Better Proxy?
No. A different subnet doesn’t automatically mean a better proxy.
An IP can come from another range and still have poor reputation, high latency, unstable routing, or the wrong location. That’s why we wouldn’t judge proxies by subnet count alone.
Our recent guide to IP reputation in sneaker botting gets into this exact problem. A proxy can work technically, but its IP may still carry signals that attract more scrutiny.
The useful checklist is broader: subnet diversity, reputation, location, speed, stability, and how those proxies actually behave on your target site.
Do Proxy Subnets Matter for Every Sneaker Release Type?
Yes, but how much they matter depends on the release and retailer.
FCFS, raffles, and queues don’t behave the same way. Our sneaker release methods guide explains how FCFS rewards successfully processed orders while inventory remains, raffles use entry windows, and queues put shoppers through a waiting or processing system.
That changes how long tasks run and how the retailer handles traffic. Your setup for a fast FCFS drop won’t necessarily behave like one built around longer sessions or raffle entries.
There ain’t one magic proxy-to-task formula that fits every release.
Can Good Proxy Subnets Stop Sneaker Bot Detection?
No. A diverse proxy pool cannot guarantee that a sneaker bot avoids detection.
Changing an IP doesn’t automatically change everything else the retailer sees. Browser characteristics can provide another identification layer, which we break down in our newer guide to browser fingerprinting for sneaker botting.
That’s the big point here. Proxy subnets tell you how your addresses are grouped at the network level. They’re useful when judging whether a pool is genuinely diverse, but they sit beside IP reputation, location, stability, fingerprints, accounts, and task behavior.
So when somebody flexes a pool of 1,000 proxies, don’t stop at the number. Check what those IPs actually look like underneath.
Proxy subnets might sound like deep tech, but they’re really just another piece of the puzzle behind a well-rounded sneaker botting setup. With 1M+ items secured and $50M+ in profit generated by members overall, TSB has built a track record across plenty of limited releases.
If you’re connecting the dots and building out your own setup, your TSB key can be another piece worth plugging into the mix.
