Best /24 ISP Subnet Proxy Providers in 2026 (Ranked)

The best ISP subnet proxy provider in 2026 is CleanProxies: you get a whole, dedicated /24 block of real US ISP IPs on Tier-1 carrier ASNs, unlimited bandwidth and threads, 100Gbps network ports, under 20ms latency and 99.9% uptime, as low as $1.19/IP for subnets (and as low as $0.75/IP if you only need individual ISP proxies). Most "ISP proxy" sellers only hand you scattered IPs that sit next to other customers. Very few sell a full /24 that is yours alone, and that difference decides whether one bad neighbour can get your whole range flagged.

If you run ad verification, SEO monitoring, multi-account operations or large scraping jobs, you have probably hit the same wall: proxies that tested clean on day one start failing in week two, and you can't tell why. Very often the reason is the subnet. Anti-bot systems score IPs by their /24 neighbourhood, so if someone else on "your" range abuses it, your traffic pays the price. Owning the subnet removes that risk.

This guide ranks the providers that sell ISP proxies in bulk or as subnets, explains what a /24 actually gives you, and shows how to test a block before you commit.

TL;DR

• CleanProxies is the #1 pick for /24 ISP subnets: dedicated blocks of 255, 510 or 1,020 IPs, as low as $1.19/IP, unlimited bandwidth, 100Gbps ports, <20ms latency, 0 fraud score IPs, HTTP(S) and SOCKS5, 24/7 support. Run by the team behind BartProxies.

• Most competitors sell single ISP IPs, not subnets, and several share each IP with up to 3 customers or cap traffic with "fair use" rules.

• The one other seller with a private /24 tops out at 254 IPs, 10 Gbps and two locations, with username:password auth only.

• Test any block with a $4.99 trial before buying: start the CleanProxies trial.

What is an ISP subnet proxy?

An ISP proxy is a static IP address registered to a consumer internet provider but hosted on fast data centre hardware. Websites see a residential-looking ASN; you get data centre speed and an IP that never changes.

A subnet proxy takes that one step further. Instead of buying 50 random ISP IPs that may be spread across ranges shared with other customers, you lease a whole /24 block: every address that shares the same first three octets (for example 203.0.113.0 to 203.0.113.255). A /24 contains 256 addresses; after the network and broadcast addresses you get the usable 254–255 proxies.

We cover the networking side in depth in What Are ISP Subnet Proxies? A Guide to /24 Proxy Blocks. The short version:

• Single ISP IPs: you control the IP, not its neighbours.

• A dedicated /24: you control the IP and every neighbour, so the range's reputation depends only on how you use it.

Why buy a whole subnet instead of single IPs?

1. Reputation isolation

Fraud and bot-detection vendors rarely judge one IP in isolation. They aggregate abuse reports, blocklist hits and bot scores at the /24 level, because abusers tend to rotate through neighbouring addresses. If one tenant on a shared range runs credential stuffing, the whole range can get a worse score. With a dedicated subnet, there is no other tenant.

2. Predictable scale

A 1,020-IP plan gives you four clean /24 blocks you can map to teams, clients or projects. That makes it easy to separate ad-verification traffic from scraping traffic, or one agency client from another, without any cross-contamination.

3. Better economics at volume

Per-IP pricing drops as blocks get bigger. On CleanProxies, subnets go as low as $1.19/IP with unlimited bandwidth included, so cost per request falls the harder you use them. There are no per-GB overages to budget for.

4. Simpler allow-listing

Partners, APIs and internal firewalls can allow-list a single CIDR (x.x.x.0/24) instead of hundreds of individual addresses. That saves time every time you rotate an IP inside the block.

5. Full control over rotation

Need to rotate? Move traffic between IPs in your own block. Every IP you rotate to has the same clean history, because nobody else has touched it.

Key stats: why subnet ownership matters in 2026

• Bots are now the majority of web traffic. Imperva's 2025 Bad Bot Report found automated traffic reached 51% of all web traffic in 2024, with malicious bots at 37%, up from 32% the year before (Imperva via TechRadar). Retail (59% bad bots) and travel (41%) are the most targeted sectors, which is why those sites score IP ranges aggressively.

• Buying your own /24 is expensive. IPv4Center's Q3 2025 market report puts the purchase price of a /24 at roughly $6,740, and the full-year 2025 average at $27.75 per IP across 901 deals (IPv4Center). That's before you pay for a server, BGP announcement, proxy software and abuse handling.

• Neighbours matter. Proxyway's subnet guide warns that sites often block IPs that share the same first three octets, and recommends a private subnet so you're the only user of the range (Proxyway).

Put simply: owning the range yourself costs thousands up front plus engineering time, and sharing a range means inheriting someone else's reputation. A dedicated subnet from a proxy provider is the middle path, and the provider's network quality decides how good it is.

The best ISP subnet proxy providers, ranked

1. CleanProxies: best ISP subnet proxies overall

CleanProxies is built around US ISP proxies, and its subnet product is the cleanest way to get a whole /24 that nobody else touches. Each block is provisioned for you, held for the life of your plan, and never resold, rotated out or added to a shared pool.

What you get

• Dedicated /24 blocks of 255, 510 or 1,020 IPs (one, two or four subnets). Bigger allocations are available through sales.

• Real US ISP IPs on Tier-1 carrier ASNs, so sites see consumer broadband, not hosting ranges.

• 0 fraud score, super clean IPs: the ranges are kept off abuse lists, so you start with a spotless history.

• Unlimited bandwidth and unlimited threads: no per-GB billing, no throttling, no overage fees.

• 100Gbps network ports and <20ms latency from our own cage and circuits.

• 99.9% uptime on infrastructure run by the same team as BartProxies.

• HTTP(S) and SOCKS5, with IP:port allow-listing or username:password authentication, switchable from the dashboard.

• 24/7 support from people who run the network, not a reseller ticket queue.

Pricing

Subnets go as low as $1.19/IP, with unlimited bandwidth included. If you don't need a full block yet, individual ISP proxies start as low as $0.75/IP, the cheapest pricing in the market. Full price tables live on the pricing page.

Why it's #1

CleanProxies is the only provider in this list that combines whole /24 blocks, sizes up to 1,020 IPs off the shelf, 100Gbps ports and unlimited bandwidth with no fair-use cut-offs. It's the best pick for agencies, ad-verification teams, SEO platforms, e-commerce monitoring and anyone who needs hundreds of IPs that behave the same on day 90 as on day one.

Best for: ad verification, SEO and SERP monitoring, multi-accounting, price aggregation, web scraping and AI agents at scale.

2. HypeProxies

HypeProxies sells dedicated ISP proxies in packs of 50 and 100 IPs and one private /24 tier of 254 IPs, in Ashburn, Virginia and Dallas, Texas (HypeProxies ISP proxies).

Where it falls short

• Network tops out at 10 Gbps, a tenth of CleanProxies' 100Gbps ports.

• One /24 is the ceiling on the self-serve plans; anything over 254 IPs needs a custom quote.

• No IP allow-listing: authentication is username:password only, which complicates some automation stacks.

• Unlimited bandwidth and threads are "subject to the Acceptable Use Policy".

• Refunds only cover technical issues within 3 days of the first purchase.

• The trial needs a request form instead of a self-serve checkout.

3. Geonode

Geonode sells dedicated ISP proxies by the IP, with tiered pricing that starts at $1.75/IP for 3–4 IPs (Geonode ISP proxies).

Where it falls short

• No full-subnet option is listed on its ISP product page, so you can't guarantee your neighbours.

• Its page notes that shared IPs can be used by up to three customers.

• Specific ISP, ASN or location combinations are not guaranteed and depend on stock at purchase time.

• No free trial or sample IPs.

4. Oxylabs

Oxylabs is an enterprise data company with a large ISP proxy line, priced per IP with volume tiers starting at $1.50/IP (Oxylabs ISP pricing).

Where it falls short

• ISP IPs are "shared with up to 3 users", the opposite of a private subnet.

• "Unlimited bandwidth with fair usage" means each IP gets 100 concurrent sessions until it hits 50 GB in a billing cycle, then drops to 10 sessions for the rest of the month.

• Some targets are restricted and may require KYC before you can use them.

• Enterprise plans start at $2,500/month.

See CleanProxies vs Oxylabs for the full comparison.

5. IPRoyal

IPRoyal sells ISP proxies by duration, starting from $2.70 per proxy for 30 days (IPRoyal ISP pricing).

Where it falls short

• Its ISP pricing page doesn't describe /24 blocks or subnet ownership.

• At $2.70/proxy, a 255-IP footprint costs far more than a CleanProxies subnet.

• Bandwidth terms aren't stated on the pricing page.

6. Rayobyte

Rayobyte's static ISP proxies are priced at $5.00/IP for 5–99 IPs, $4.80 for 100–999 and $4.60 for 1,000–4,999 per month (Rayobyte ISP proxies).

Where it falls short

• No whole-subnet product on its ISP page.

• Traffic is unmetered but "fair usage applies".

• Static IPs are excluded from the self-serve free trial; you have to contact sales.

• A 1,000-IP footprint costs roughly four times what a CleanProxies 1,020-IP subnet plan does.

What about buying or leasing a raw /24 yourself?

Some teams consider skipping proxy providers and acquiring IPv4 space directly. It works, but it's a different business:

The killer detail is the ASN. A range you buy and announce from a hosting provider shows up as hosting, not ISP, which defeats the whole point of ISP proxies.

What the numbers mean

• Dedicated beats shared, every time. "Shared with up to 3 users" means up to three different traffic patterns on one IP. On a dedicated subnet, every request on the range is yours.

• Unlimited has to mean unlimited. A 50 GB fair-use threshold sounds generous until a scraping job pushes 2 TB a month across 255 IPs. CleanProxies subnets have no bandwidth cap or throttle.

• Network capacity sets your ceiling. 100Gbps ports vs 10 Gbps is the difference between saturating your scrapers and saturating the proxy.

• Per-IP price is only half the story. Price × IPs + overages + failed requests is your real cost. Clean, never-shared ranges fail less, so the effective price per successful request drops further. Run your own numbers with the proxy cost calculator or read How Much Do Proxies Cost in 2026?.

Which ISP subnet provider should you pick?

• You need one or more full /24s with zero neighbours: CleanProxies. Pick 255, 510 or 1,020 IPs and scale through sales beyond that.

• You need the lowest cost per IP at volume: CleanProxies, as low as $1.19/IP on subnets with unlimited bandwidth, or as low as $0.75/IP for individual ISP proxies.

• You need IP allow-listing for servers or partners: CleanProxies supports IP:port and user:pass auth; HypeProxies supports user:pass only.

• You push heavy traffic: CleanProxies, with 100Gbps ports and no 50 GB fair-use cut-off.

• You're comparing many providers at once: see the CleanProxies comparison hub, our best ISP proxy providers ranking and cheapest ISP proxies price table.

How to test an ISP subnet before you commit

Never buy hundreds of IPs without checking a sample. Here's the checklist we use:

1. Confirm the ASN type. Run a few IPs through the IP lookup tool. The organisation should be a consumer ISP, not a hosting company.

2. Check blocklists. Paste the IPs into the IP blacklist checker. A clean range has zero hits across major DNSBLs.

3. Test speed and anonymity. The proxy checker shows latency, protocol support and whether headers leak your real IP.

4. Look for leaks in the browser. If you use antidetect browsers, run the WebRTC leak test through the proxy.

5. Verify the CIDR. All IPs in a /24 plan should share the first three octets. If they don't, it isn't a subnet.

6. Run your real workload for an hour. Success rate on your actual targets is the only metric that matters. Avoid the common proxy mistakes that cause bans while you test.

7. Start with the $4.99 trial. CleanProxies gives you 5 ISP IPs for 1 hour, or 100 MB, for $4.99, so you can test the same network your subnet runs on. Start your $4.99 trial.
