Best ISP Proxy Providers Compared on Price, Pools and Uptime

If you read nothing else: buy the cheapest IP class that passes your target, not the most expensive one that definitely will. The test in Run a 48-hour test saves more money than any discount code.

An ISP proxy is a static IP that lives on datacenter hardware but sits in a netblock registered to a consumer internet provider. When a target does a WHOIS or ASN lookup on your exit IP, it sees a residential carrier instead of a hosting company. The server, the port, the routing, and usually the speed are identical to a datacenter proxy. The mechanics are covered in what ISP proxies are and the head-to-head in ISP proxies vs datacenter proxies.

The premium buys exactly three things:

1. ASN registration. The IP resolves to a consumer ISP instead of a cloud host.
2. Exclusivity. Nobody else is hammering the same IP against the same target.
3. Tenure. How long you can hold that specific address before it rotates away or gets reclaimed.

Everything else on the feature list is packaging. Judge vendors on how well they deliver those three, and on what your bill looks like at 5x your current volume.

1. Dedicated or shared

A "static residential" IP that three other customers also point at the same platform is not worth ISP money. Ask directly: is this address assigned to my account exclusively for the billing period, and is there a shared tier I might be silently moved into during a capacity crunch? Get the answer in writing before you scale past a handful of IPs. The same logic one tier down is in shared vs dedicated datacenter proxies.

2. ASN and subnet spread

Fifty IPs that all sit in one /24 under one ASN behave like one IP to a competent defender. Subnet-level blocking is standard practice now, which is why clean subnets and IP fingerprinting matter more than raw count. Ask how many distinct /24s and how many distinct ASNs your allocation will span in the country you actually need.

3. Billing shape

Per IP per month, per GB, or a hybrid. This decides whether cost scales with account count or with page weight, and the two grow at wildly different rates.

4. Replacement policy

IPs die. They get flagged, reclaimed by the upstream carrier, or land on a blocklist through no fault of yours. The question is who pays. Some vendors replace on request inside a window, some charge, and some replace only if you prove the IP is dead network-wide rather than dead on your one target. That last variant is close to worthless for account work.

5. Geographic depth where you need it

"195 countries" on a landing page usually means a handful of addresses exist in most of them. If your workload is Germany, ask for the German count and the German ASN list. Country coverage is a marketing number. Per-country depth is the buying number.

Everything below describes each vendor's own published positioning as of September 2026. Proxy pricing and product names change quarterly, and several of these companies have rebranded or restructured plans in the last two years. Check the vendor's own pricing page before you buy, and treat any figure in a listicle, this one included, as a starting point for your own quote.

Three groupings fall out of that table. Enterprise vendors (Bright Data, Oxylabs) are the right call when a security questionnaire, a data processing agreement, and net-30 invoicing are part of the purchase. You are paying for the paperwork as much as the packets, and for many companies that is a legitimate cost. Self-serve mid-market (Decodo, SOAX) suits a team of two to twenty that wants a dashboard, an API, and card payment today. Budget tier (IPRoyal, Rayobyte, Webshare, Proxy-Cheap) is where you go when you need 10 to 100 static IPs and the compliance overhead of the enterprise tier buys you nothing.

Three shapes exist, and each has a different trap.

Per IP per month is the honest one for account work. You know your bill on day one: IP count times unit price. Across public pricing pages in September 2026, dedicated ISP IPs commonly list in the low single-digit dollars per IP per month, with steep discounts above 100 IPs and premiums for scarce geographies. Confirm the current figure on the vendor's site, because these move.

Per GB is the trap for scraping. ISP bandwidth is priced well above datacenter bandwidth, and page weight is not under your control. A product page that ships 4 MB of images and JavaScript costs 4 MB whether you wanted the price field or the whole DOM. Ten thousand of those is 40 GB for a job that returns a few megabytes of useful data. The arithmetic is worked through in datacenter proxy pricing models.

Hybrid plans bundle N IPs plus a bandwidth allowance, then charge overage. Read the overage rate, not the headline. Overage is where hybrid plans make their margin.

For contrast, here is SparkProxy's own published datacenter pricing. Every tier is unlimited bandwidth with 30 days validity:

Speed figures are fair-usage ceilings, not guaranteed throughput. Higher Pro and Pro+ thread tiers exist under the same policy without public pricing. The reason for printing this beside an ISP discussion: if your target does not inspect ASN, a flat unlimited-bandwidth plan removes per-GB anxiety completely, and that is the comparison most ISP buyers never run.

Nobody publishes an auditable ISP pool count. The homepage number is a claim about addresses the vendor can theoretically source, not addresses available to you, in your country, tonight. Replace it with four questions you can verify during a trial:

• How many distinct /24 subnets does my allocation touch in the country I need?
• How many distinct ASNs, and are they consumer carriers or hosting blocks announced under a consumer name?
• Can I see the actual IP list before committing, or at least a sample?
• If I order 100 more IPs in this country next month, do they come from the same subnets as the 20 I have now?

That last question predicts your future far better than a pool figure does. A vendor who can only expand you inside the same three subnets has a depth problem that surfaces exactly when you scale. Background on why ASN identity carries this much weight is in what a datacenter ASN is.

"99.9% uptime" means roughly 43 minutes of permitted downtime per month. Most ISP vendors advertise 99.9% or better, and most measure it at the gateway rather than at your individual IP. From your side of the wire those are different products.

Gateway uptime tells you whether the authentication endpoint answers. IP survival tells you whether the specific address you built an account on still works against your specific target. A vendor can hit 99.99% gateway uptime while a third of your addresses get flagged by one platform in a week, and nothing in the SLA covers that.

Ask about the second number instead. What share of dedicated IPs are replaced per month across the fleet? Is replacement self-serve in the dashboard or a support ticket? Is there a monthly cap? And when the SLA is breached, is the remedy a service credit, which is the industry norm, or something closer to compensation? Service credits cost the vendor almost nothing. Read the SLA as a statement of intent, and read the replacement policy as the term that will actually affect your month.

NetNut sits near the top of nearly every ISP proxy ranking written before 2026, because its ISP-sourced network was a real differentiator. Check the domain before following that advice. As of September 2026, a DNS lookup for netnut.io returns the nameservers ns1.fbi.seized.gov and ns2.fbi.seized.gov, the signature of a United States federal domain seizure.

We are not going to speculate about the reasons. The point for a buyer is procedural: any ranking that still lists it has not been checked since publication, and its other recommendations deserve the same suspicion. Before sending money to a vendor you found in a list, resolve the domain, check the WHOIS creation date, and confirm somebody answers a support ticket.

Reviews cannot tell you whether an IP class passes your target. Two days of your own data can. Buy the smallest possible quantity from two vendors, then run this.

First, confirm the exit is where the dashboard claims:

curl -s --proxy http://USER:PASS@gateway.sparkproxy.io:11000 https://ipinfo.io/json

Then measure the thing that matters, which is success rate against the real target rather than against a test endpoint:

import collections
import requests

PROXY = "http://USER:PASS@gateway.sparkproxy.io:11000"
TARGET = "https://your-target.example/product/12345"

codes = collections.Counter()
for _ in range(200):
    try:
        r = requests.get(TARGET, proxies={"http": PROXY, "https": PROXY}, timeout=20)
        codes[r.status_code] += 1
    except requests.RequestException:
        codes["error"] += 1

print(codes)

Run 200 requests per IP class, spread over at least 24 hours so you catch time-of-day rate limiting. Record three numbers per vendor: HTTP 200 rate, median latency, and the count of soft blocks, meaning 200 responses that carry a challenge page instead of content. Soft blocks are the ones that quietly poison datasets, because your scraper logs them as successes.

If the target needs a real browser, comparing raw proxies against a managed fetch is ten minutes well spent:

curl -s -X POST "https://scrape.sparkproxy.io/api/v1" \
  -H "X-API-Key: sk-xxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d "{\"url\":\"https://your-target.example/product/12345\",\"render_js\":true,\"country_code\":\"us\"}"

The SparkProxy Scraping API gives 1,000 free credits with no card, which is enough to benchmark a target properly. Plain fetches cost 1 credit, JavaScript rendering 5, screenshots and PDFs 10. If a managed endpoint clears your target at 1 to 5 credits per page, the ISP purchase may not be needed at all.

Skip ISP proxies entirely in these cases:

• The target never checks ASN. Plenty of public catalogues, documentation sites, job boards, and smaller ecommerce platforms do not. Test datacenter first.
• Your workload is bandwidth-heavy scraping. Per-GB ISP billing punishes page weight, and page weight is the target's decision, not yours.
• You need rotation, not tenure. If a fresh IP per request is fine, you are paying for a static property you throw away. See rotating vs static residential proxies.
• You need city or carrier granularity. That is residential or mobile territory, and the three-way trade-off is laid out in residential vs datacenter vs mobile proxy types.

Buy ISP when you hold long-lived accounts, when your own testing shows the target blocks hosting ranges, and when IP stability across weeks is the actual product requirement.

Honest positioning: SparkProxy sells datacenter proxies and a Scraping API, not ISP proxies. The network is 1M+ datacenter IPs across 80+ countries, including 50,000+ US addresses, reached through gateway.sparkproxy.io on port 11000 for HTTP and HTTPS, 11002 for sticky sessions, and 13000 for SOCKS5. Every plan is unlimited bandwidth with 30 days validity.

If your target inspects ASN and rejects hosting ranges, buy from the ISP shortlist above. That is the correct purchase and we are not going to pretend otherwise. Run the test in the other direction first, though, because a large share of buyers reach ISP pricing on the assumption that their target blocks datacenter traffic without ever measuring it. Unlimited bandwidth at $75 to $440 per month changes the arithmetic for anything scrape-shaped, and the evaluation checklist in what to evaluate when selecting a proxy service applies no matter which vendor ends up getting paid.
