Residential proxies route traffic through household devices with rotating IP addresses, while ISP proxies hold static IPs registered with internet service providers but hosted on datacenter servers. The core tradeoff is IP persistence; residential proxies rotate for stealth, ISP proxies stay static for speed and session consistency.
Choosing between them depends on your workload, anonymous rotation across 195+ countries, or a dedicated IP identity with 1Gbps+ throughput. This guide compares speed, detection resistance, geo-targeting, pricing, and use cases so you can pick the right proxy type for every task.
Which Proxy Type Should You Pick?
Choose residential proxies if you need rotating IPs for large-scale web scraping, ad verification across multiple countries, price monitoring, or any task targeting sites with aggressive anti-bot detection. Residential IPs come from verified household devices, carry the highest trust scores, and rotate automatically to avoid blocks.
Choose ISP proxies if you need a static residential IP for account management, sneaker bots, SEO monitoring, or long-running browser automation. ISP proxies deliver datacenter-grade speed with a residential ASN, giving you a consistent identity that doesn’t trigger login security flags.

What Separates Residential Proxies From ISP Proxies?
Residential proxies pull IP addresses from household devices, desktops, laptops, and phones on home internet, and rotate those IPs automatically with each request or at set intervals. ISP proxies use IP addresses assigned by internet service providers like Comcast, AT&T, or Spectrum, but host those IPs on datacenter servers instead of home devices.
How Residential Proxy Architecture Works
Residential proxies operate through peer-to-peer networks where opted-in users consent to share their connection. PlainProxies maintains a pool of 25M+ residential IPs across 195+ countries, supporting up to 50,000 concurrent connections with city and state-level geo-targeting. Because each IP belongs to a verified household, target websites treat residential proxy traffic as ordinary browsing activity. IPs rotate automatically, either per request or through sticky sessions lasting up to 24 hours.
How ISP Proxy Architecture Works
ISP proxies, also called static residential proxies, blend residential authenticity with datacenter performance. Each IP carries a residential ASN number (websites see it as a home connection), but datacenter hosting delivers 1Gbps+ speeds with sub-50ms latency. The IP is dedicated to you alone, fixed and static, for as long as you hold it.
If you see “static residential proxies” and “ISP proxies” listed as separate products, they’re the same thing; the proxy industry uses both names interchangeably.
The fundamental difference is IP persistence. Residential proxies rotate. ISP proxies stay static. Every other difference, speed, detection, pricing, geo-targeting, flows from that single architectural decision.
Speed and Stability: ISP Proxies vs Residential Proxies
ISP proxies deliver datacenter-grade performance with dedicated bandwidth allocation. PlainProxies ISP proxies run at 1Gbps+ throughput, sub-50ms latency, and a 99.99% uptime SLA. Connection quality stays consistent because there’s no dependency on end-user home Wi-Fi.
Residential proxy speeds vary by connection. Each request routes through an end-user’s device, so throughput depends on that household’s internet quality. PlainProxies residential proxies maintain 99.9% uptime and offset per-connection variability by supporting 50,000 simultaneous threads. If one connection drops, the rotation engine assigns a fresh IP instantly.
Which One Is Faster?
ISP proxies win on raw speed every time. For checkout flows, monitoring dashboards, and long-running browser automation, the static datacenter connection eliminates latency spikes. Residential proxies compensate for individual speed variance with massive concurrency, tens of thousands of parallel requests spread across a 25M+ IP pool.
Detection Resistance: Which Proxy Type Survives Anti-Bot Systems?
Residential proxies carry the highest trust score of any proxy type because every IP originates from a verified household device with a unique subnet footprint. Anti-bot systems, browser fingerprinting, behavioral analysis, and CAPTCHA challenges struggle to distinguish residential proxy traffic from organic visitors.
ISP proxies sit one tier below. The residential ASN fools basic and moderate security, but advanced fingerprinting can identify datacenter hosting behind the residential ASN.
Subnet Diversity and Blacklist Risk
Residential proxies rarely share subnets. Blocking one IP doesn’t expose others in the pool. ISP proxies group IPs in ranges. If a target blacklists one IP in a subnet, other IPs in that range face higher scrutiny.
What Happens When an IP Gets Flagged?
With ISP proxies, a flagged static IP means all activity on that address stops. No automatic failover. With residential proxies, the rotation engine assigns a new IP from the pool, and operations continue uninterrupted.
PlainProxies residential proxies also support sticky sessions up to 24 hours, bridging the gap for tasks needing both stealth and session continuity.
Sites with aggressive bot detection (social media, ticketing, sneaker drops) require residential rotation. Sites with standard security work reliably with ISP static IPs.
Geo-Targeting and IP Pool Size Compared
Residential proxies cover 195+ countries with city and state-level targeting from a 25M+ IP pool. This makes residential proxies the default for ad verification across regions, localized pricing data, or accessing geo-restricted content.
ISP proxies connect faster but from fewer locations. PlainProxies ISP proxies operate from Auburn, Alabama (US), making them strong for US-focused tasks but limited for global multi-country campaigns. If your workload requires IPs across dozens of countries simultaneously, residential proxies handle that natively.
Use Cases: When to Choose ISP vs Residential Proxies
ISP proxies outperform residential proxies for tasks requiring a consistent IP identity. Residential proxies dominate use cases needing rotating IPs across global locations.
When ISP Proxies Are the Right Choice
Account management and multi-login operations: Social media accounts and e-commerce dashboards track login IPs. Rotating residential IPs triggers security verification on every session. ISP proxies hold a static residential IP that maintains your identity without flagging security.
Sneaker bots and limited-edition purchases: Checkout flows need speed and session consistency. ISP proxies deliver 1Gbps+ throughput without rotating mid-purchase.
SEO monitoring: Same IP eliminates personalization variance that skews SERP tracking.
Long browser automation: Workflows running for hours need a connection that won’t cycle IPs mid-session.
When Residential Proxies Are the Right Choice
Large-scale web scraping (10,000+ pages/day): Rotating IPs prevents rate limiting. Each request uses a different address from the 25M+ residential pool, making throttling nearly impossible.
Price monitoring and competitor tracking: Static IPs get rate-limited fast on e-commerce sites. Rotating residential IPs collect pricing data without triggering blocks.
Ad verification across regions: Checking ad placements in multiple markets requires geo-targeted IPs. Residential proxies cover 195+ countries at city-level precision.
Scraping sites with aggressive anti-bot detection: Social media platforms, travel aggregators, and real estate portals use advanced fingerprinting that only household-sourced residential IPs reliably pass.
Pricing: Per-GB vs Per-IP and Which Saves Money
ISP proxies charge per-IP with unlimited bandwidth included. Residential proxies charge per GB of data transferred. The cheaper option depends on data consumption.
Per-IP Pricing (ISP Proxies)
Flat rate per static IP per month. Data transfer is unlimited, your bill stays the same if you push 10GB or 500GB. Cost-efficient for high-bandwidth operations like continuous monitoring or scraping content-rich pages.
Per-GB Pricing (Residential Proxies)
Lower entry cost that scales with usage. Targeted scraping with optimized page loads (disabling images/scripts) keeps costs manageable. Heavy usage adds up fast, scraping 50,000 pages at 500KB each burns through 25GB per day.
For high-volume operations, PlainProxies also offers unlimited residential proxies, flat-rate pricing with no bandwidth caps, combining rotating IP stealth with predictable costs.
Common Mistakes When Choosing Between Residential and ISP Proxies
Choosing the wrong proxy type wastes budget on blocked requests and broken sessions.
- Using rotating residential for account management, every IP change triggers security flags. Use ISP static IPs instead.
- Using ISP proxies for scraping across 20+ countries, limited geo-coverage, and static IPs get rate-limited fast. Use residential rotating IPs.
- Running per-GB residential on unoptimized pages, 500KB+ page loads burn bandwidth in days. Strip unnecessary elements or switch to unlimited residential.
- Manually rotating a static IP list to mimic residential behavior, predictable cycling patterns are detectable. Residential pools with 25M+ addresses randomize selections across millions of IPs.

Frequently Asked Questions
Are ISP proxies the same as static residential proxies?
ISP proxies and static residential proxies are the same product. Both use IP addresses assigned by internet service providers, hosted on datacenter servers. The “static residential” label reflects that the IP appears residential while remaining fixed rather than rotating.
Which proxy type is cheaper for large-scale web scraping?
Per-GB residential pricing works for lightweight, optimized requests. For heavy scraping (50,000+ pages daily), ISP proxies with unlimited bandwidth or unlimited residential plans remove the per-GB cost ceiling.
Do ISP proxies work for sneaker bots?
ISP proxies are the preferred choice for sneaker bots. The static IP maintains session consistency through checkout, and 1Gbps+ speeds reduce latency during high-demand releases.
How does IP rotation differ between residential and ISP proxies?
Residential proxies rotate IPs automatically, per request or at configurable intervals, using session IDs (000000–999999). ISP proxies do not rotate. You receive a dedicated static IP that stays yours until you cancel or request a change.
Can I use both ISP and residential proxies together?
Running both is a common setup. Assign ISP proxies to account sessions and checkout flows. Route scraping and ad verification through residential proxies. PlainProxies supports both through the same dashboard with shared authentication and protocols.
Are residential proxies legal and ethically sourced?
Residential proxies are legal when IPs come from users who explicitly consent. PlainProxies sources all residential IPs through opt-in, compensated partnerships with full GDPR and CCPA compliance.
