AceShowbiz - If you have ever bought a stack of IPv4 proxies and watched half of them get flagged in the first week, you already know the punchline of this article: pool size is not the metric that matters. Subnet diversity is.

The mistake is common. A developer buys 100 IPs from a cheap provider, plugs them into a scraper or a testing pipeline, and everything works for two days. Then a target site blocks one address, and forty more addresses stop working at the same time, because they all live in the same /24 subnet, and the site’s anti-bot layer blocked the range, not the individual IP.

For a front-end developer testing geo-specific rendering, an SEO analyst checking SERPs, or a QA engineer running headless browser tests at scale, that difference is the difference between a stable workflow and one that requires weekly re-purchasing. Below is a look at the five IPv4 providers worth considering in 2026 and how they compare on the two things that actually determine how long your addresses stay useful.

What Subnet Diversity Actually Means

A subnet is a contiguous block of IP addresses that share a network range. If a site’s anti-bot system flags one IP inside a /24, it very often flags the whole /24. That is the entire mechanism behind the “why did all my proxies die at once” experience.

Good subnet diversity means the addresses you buy are spread across many different subnets. Bad subnet diversity means you own 100 IPs that share three subnets, and one blocking decision on the target side takes 33 of them offline.

You cannot tell the difference from a provider’s landing page. You can only tell by looking at the actual addresses they assign you, or by reading tests that others have run.

The Five Providers in the 2026 Ranking

1. ProxyWing

If you want high subnet diversity without paying enterprise rates, this is where most developers should start. Around 70 million IPv4 addresses across 195+ locations, running on a 1 Gbps backbone. Subnets stay isolated, flagged IPs are replaced automatically, and the pool holds its cleanliness over time.

Both HTTP and SOCKS5 supported, 99.9% uptime, and support that averages about a minute on response time. Plans start at $0.90/month for datacenter IPv4, $1.70/month for ISP-grade IPs, and $2.50/GB for residential proxies. Best overall pick for teams that want quality without a six-figure commitment.

2. Bright Data

One of the largest IPv4 networks in the market. 72M+ total IPs, 1.6M of them dedicated datacenter across 98 countries, and dedicated datacenter distribution across roughly 3,000 subnets. Targeting is granular down to city, ASN and ZIP code level. HTTP/HTTPS and SOCKS5 both supported.

Pricing is enterprise-tier and only starts to feel reasonable at higher volumes or when you are also using their higher-end features like the proxy manager or Web Unlocker.

3. Oxylabs

Also one of the biggest IPv4 pools available. 177M+ proxies of all types, 2M+ dedicated datacenter across 188 locations. Subnet diversity is strong, IPs are pre-tested against major targets, and average response time hovers around 0.6 seconds.

Unlimited bandwidth, city-level targeting, both HTTP/HTTPS and SOCKS5. Datacenter starts at $1.20 per IP, but the full self-service plans require heavier commitments, Oxylabs is more suited to real workloads than small side projects.

4. IPRoyal

Dedicated IPv4 datacenter proxies starting at $1.39 per IP with unlimited bandwidth and city targeting. All datacenter proxies are IPv4, and buyers can request specific subnets through the Extra Requirements feature at order time.

Overall network is 32M+ IPs across 195 countries. Subnet diversity on the datacenter pool is not as broad as with the enterprise providers, which can be a problem for platforms with aggressive ASN filtering, but for standard workloads at this price it holds up well.

5. Webshare

Shared, private and dedicated tiers across 50+ countries, starting at $0.018 per proxy. HTTP, HTTPS and SOCKS5 supported, network is 80M+ IPs, uptime around 99.97%.

The dashboard lets you filter proxies by subnet diversity, but actual testing shows 50 IPs sometimes coming from just 8 different /24s, which is thinner than the price implies. Fine for testing or low-stakes tasks, weaker on difficult targets.

Subnet Variety and IP Cleanliness

ProxyWing

isolates subnets across its 70M+ pool and swaps out flagged IPs automatically. The combination is what makes it viable at a non-enterprise price point.

Bright Data

has one of the widest subnet spreads on the market, with dedicated datacenter IPs spanning around 3,000 subnets. The pool is large enough that individual addresses do not get overused.

Oxylabs

runs one of the cleanest IPv4 networks available. Pre-testing against common targets and the 2M+ dedicated datacenter distribution give it strong subnet diversity by default.

IPRoyal

is respectable on cleanliness for its tier, particularly because the IPs on dedicated plans are not shared. Subnet variety is thinner than the enterprise pool leaders, but the ability to specify subnets at order time gives buyers unusual control at this price.

Webshare

cleanliness is reasonable on private and dedicated plans and weaker on shared. Testing has shown 50 IPs originating from as few as 8 different /24s, meaning a single subnet ban can take multiple addresses down at once.

Pricing and Volume Discounts

• ProxyWing. $0.90/IP/month starting, with meaningful volume discounts and additional savings on 3-, 6- or 12-month contracts.
• Bright Data. Pay-as-you-go or committed plans, datacenter starting at $1.40/IP. Enterprise plans deliver much larger discounts at high volume.
• Oxylabs. From $1.20/IP with unlimited bandwidth. Self-service plans require higher commitment; dedicated datacenter plans start around $12/month.
• IPRoyal. From $1.39/IP with 30/60/90-day billing cycles and unlimited bandwidth on dedicated datacenter.
• Webshare. $0.018/proxy at the lowest tier and 30% off with annual billing. The savings come with the subnet diversity trade-offs on shared plans.

Picking the Right Provider for Your Workflow

Most developers should start with ProxyWing. It covers the widest range of workflows, has clean subnets, and its pricing does not force you into large commitments before you know what you actually need.

Bright Data and Oxylabs are the correct answers if you are on an enterprise team that needs top-tier targeting and the largest IPv4 networks. Both come with meaningful budget requirements.

IPRoyal fits developers who want per-IP pricing, unlimited bandwidth and the ability to specify subnets at order time. Webshare is the cheapest way in and works fine for testing and low-stakes tasks, but its subnet spread starts limiting the harder use cases quickly.

Closing Thoughts

Every provider on this list is a fit for a different kind of buyer, and the right choice depends on how large your workloads are and how aggressively the sites you target actually respond to bot signals.

ProxyWing offers the most economical, high-quality and subnet-diverse combination for most developers in 2026 without an enterprise contract. Bright Data and Oxylabs remain the safer bets for infrastructure built for large scale. IPRoyal and Webshare each carve out a niche at the lower end.

Whichever direction you go, the practical advice stays the same: test before you commit. A weekend of running your actual pipeline against 20 IPs from a trial will tell you more than any comparison table, this one included.
