ISP Proxies: The Complete Guide to Static Residential IPs

What are ISP proxies?

ISP proxies are proxies that use IP addresses registered to consumer internet service providers, such as Comcast, AT&T, Verizon, Charter or Cox in the US, but hosted on servers in data centres. They're also called static residential proxies.

The result is a hybrid. In IP intelligence databases, the address looks residential, because the ASN belongs to an ISP. In practice, the proxy runs on fast, stable server hardware with a dedicated connection, so you get datacenter-like speed and an IP that never changes.

How ISP proxies are made

Providers obtain IP ranges that are registered to ISPs, typically through business arrangements with ISPs or with companies holding ISP-registered address space, and announce those ranges from their own infrastructure. Because the IPs aren't attached to real household devices, they don't go offline when someone switches off a router.

Why ISP proxies are so popular

• High trust. Websites see a consumer ISP, not a hosting company.
• Speed. Server-grade connections and low latency.
• Static IPs. Same IP for as long as you rent it, ideal for accounts and checkouts.
• Predictable cost. Priced per IP rather than per GB, often with unlimited bandwidth.

This combination makes them the standard sneaker proxies for footsites and Shopify, and a top choice for social media account management, e-commerce seller accounts and long browser sessions.

Weaknesses

• Smaller pools. Providers have thousands, not millions, of ISP IPs.
• Less location choice. Usually a handful of countries and limited city options.
• Subnet clustering. ISP proxies often come from a few subnets. If a site flags a subnet, everyone on it suffers.
• Detectable patterns. Sophisticated systems can notice that an "ISP" IP behaves like a server: no typical consumer traffic, server-like TCP fingerprints, and hosting-like latency.
• Not rotating by default. For many-IP scraping, rotating residential is usually better.

Best use cases

• Sneakers. Footsites, Shopify and many release sites. See ISP proxies for sneakers.
• Social media management. One static IP per account. See social media management proxies.
• E-commerce seller accounts on marketplaces.
• Ad accounts that need consistent login locations.
• Long-running browser sessions with Puppeteer or Playwright.
• Whitelisted access to services that only accept known IPs.

Pricing

ISP proxies are sold per IP, typically monthly, with daily and weekly options common in the sneaker market. Rough market ranges at the time of writing are $1.50 to $4 per IP per month at small volumes, and below $2 per IP at larger volumes. Sneaker-focused "premium" ISP subnets can cost more around big releases.

How to choose an ISP proxy provider

1. Which ISPs (ASNs) do the IPs come from? Big-name consumer ISPs are better.
2. How many subnets will your IPs span?
3. Are the IPs dedicated to you or shared?
4. Which locations are available? Match your targets.
5. What's the replacement policy for banned IPs?
6. Is bandwidth unlimited?
7. Do they offer daily or weekly terms for sneaker releases?

Testing an ISP proxy batch

When you receive ISP proxies, run through this quickly:

1. ASN check: look up a sample. Is it a well-known consumer ISP?
2. Location check: does it match what you ordered?
3. Subnet count: how many distinct /24s?
4. Reputation: check a few on blocklists.
5. Speed: measure from your server. See proxy speed test.
6. Target test: low-volume requests to your real target.

ISP proxies for scraping: when they shine

ISP proxies are underrated for scraping in a few situations:

• Browser-based scraping where bandwidth would make residential expensive.
• Logged-in scraping of data you're authorised to access, where you need a stable IP.
• Moderate-volume scraping of protected sites where a few dozen trusted IPs, used politely, are enough.

They're less suited to massive crawls needing thousands of distinct IPs per hour.

Ethics and sourcing

ISP proxies don't use consumer devices, so the consent issues of residential networks don't apply in the same way. Still, ask how the provider obtained the IP space and whether it's properly registered. See how proxy providers source IPs.

Running a 30-day ISP proxy pilot

ISP proxies are usually bought monthly, so your first month is effectively the trial. Use it deliberately:

A few habits make the pilot meaningful:

• Tag every request with the proxy IP, so you can rank individual IPs and subnets, not just the batch.
• Keep the control group honest: same targets, same times, same client settings.
• Ask about replacements before week 4. Some sellers only replace IPs early in the rental period.
• Note each IP's network and registered location on day one, so you'll notice if anything changes at renewal.

At the end, you'll know whether the batch earns its price. Compare your numbers with best ISP proxies and ISP proxy providers compared. If results are mixed, ISP vs residential proxies explains when a blend of the two works better than either alone.

FAQ

Are ISP proxies residential proxies?

They're registered as residential but hosted in data centres. That's why they're often called static residential proxies.

Can ISP proxies rotate?

Some providers offer rotating ISP pools, but most ISP proxies are sold as static IPs.

Are ISP proxies good for web scraping?

For moderate volumes on protected sites, yes. For millions of requests needing huge IP diversity, rotating residential is usually better. See best proxies for web scraping.
