Residential proxies and datacenter proxies route traffic through different IP infrastructures, and that difference controls detection risk, speed, cost, and success rate on every target. Residential proxies use IP addresses assigned by Internet Service Providers to real household devices, making them nearly impossible for anti-bot systems to distinguish from genuine users. Datacenter proxies use IPs hosted on cloud servers and data center infrastructure, delivering up to 10Gbps speeds at a lower cost but facing a higher detection risk on protected websites.
PlainProxies operates both residential proxy pools (25M+ IPs, 195+ countries) and datacenter proxy networks (15,000+ IPs, 99.99% uptime), so teams match proxy type to target without switching providers.
How IP Origin Creates the Core Difference Between Residential and Datacenter Proxies
The difference between residential proxies and datacenter proxies starts at the IP source. Residential proxies carry IP addresses that Internet Service Providers like Comcast, AT&T, and Spectrum assign to actual home connections. A target website sees residential IP traffic as identical to a regular person browsing, and anti-bot systems trust it because the IP reputation traces back to a consumer ISP.
Datacenter proxies carry IPs generated by cloud servers and data center infrastructure, facilities run by hosting companies, not consumer ISPs. Every IP address belongs to an Autonomous System Number (ASN) that identifies the network owner. Anti-bot detection systems check incoming requests against ASN databases, and datacenter ASNs from providers like AWS, OVH, or Hetzner are flagged as non-residential. That flag triggers CAPTCHA responses, 403 Forbidden responses, rate limiting, or outright blacklisting.
This ASN-based IP classification is why residential proxies pass where datacenter proxies get blocked on the same target. Understanding how proxy networks manage IP rotation, sessions, and detection at the infrastructure level makes configuring either proxy type more effective.
Residential Proxies vs Datacenter Proxies Comparison
Residential and datacenter proxies differ across five comparison axes: IP source, detection risk, speed, cost structure, and use case fit.
| Feature | Residential Proxies | Datacenter Proxies |
| IP Source | ISP-assigned to real household devices | Cloud servers / data center infrastructure |
| Detection Risk | Very low, genuine residential ASN | Medium-high, ASN reveals server origin |
| Success Rate | 85–99% on protected sites | 40–60% on protected sites, 95%+ on permissive targets |
| Speed & Latency | Moderate (real household connection) | Very fast, up to 10Gbps, sub-100ms latency |
| Cost Model | Pay-per-GB (traffic-based) | Per-IP or flat monthly, often with unlimited bandwidth |
| IP Pool | Millions (PlainProxies: 25M+ IPs) | Thousands (PlainProxies: 15,000+ dedicated IPs) |
| Geo Coverage | 195+ countries, city-level geo-targeting | Select locations (US, UK, DE, NL, CA) |
| Session Types | Rotating + sticky sessions (up to 24h) | Rotating + sticky sessions |
| Protocols | HTTP(S) + SOCKS5 | HTTP(S) + SOCKS5 |
| Best For | Protected sites, ad verification, social media, geo-targeting | High-volume crawling, SEO monitoring, price tracking, QA |
Neither type is universally better. A web scraping operation targeting Cloudflare-protected e-commerce pages needs a different proxy setup than a team running SEO rank tracking across public search results.
Why Anti-Bot Systems Block Datacenter Proxies and Trust Residential IPs
Anti-bot detection platforms like Cloudflare, PerimeterX, and DataDome classify every incoming request by checking IP type against ASN databases before the connection reaches the target server. Datacenter IP ranges, registered to hosting providers and cloud infrastructure, are cataloged and flagged automatically. Requests from datacenter ASNs face CAPTCHA challenges, 403 Forbidden blocks, aggressive rate limiting, and IP blacklisting.
Residential IPs pass this first detection gate because their ASN belongs to a consumer Internet Service Provider. The anti-bot system reads the connection as a legitimate household user, not a server. That IP reputation advantage is why residential proxies sustain 85–99% success rates on targets where datacenter proxies fail 40–60% of the time.
Datacenter proxies still work on permissive targets, public APIs, government databases, and sites without aggressive bot detection that don’t scrutinize ASN classification. Residential proxies aren’t block-proof either; overusing a single IP, missing browser fingerprinting signals, or hammering the same subnet triggers detection regardless of IP type. For protected targets, residential proxies configured for bot detection bypass with proper rotation deliver the most consistent results.
Speed, Latency, and Throughput: How Proxy Performance Differs
Datacenter proxies deliver 3–4x faster response times than residential proxies because server-hosted IPs connect through fiber backbone infrastructure rather than household internet connections. PlainProxies datacenter network runs at 10Gbps with sub-100ms latency and a 99.99% uptime SLA.
Residential proxy speed varies because traffic routes through real home connections. Individual IP latency fluctuates, but residential infrastructure compensates through concurrency. PlainProxies residential proxies support 50,000 concurrent connections across thousands of parallel sessions.
The metric that matters for data operations: effective throughput. A datacenter request completing in 50ms but blocked 50% of the time delivers less usable data per hour than a residential request completing in 300ms at a 95% success rate. Fewer retries and fewer CAPTCHAs mean residential proxies achieve higher effective throughput on protected targets. On permissive targets where both types succeed equally, datacenter proxies at 10Gbps win on raw performance.
Pay-Per-GB vs Flat-Rate, How Residential and Datacenter Proxy Pricing Works
Residential proxies use pay-per-GB billing because ISP-assigned IPs are scarce and require ethical sourcing from compensated users. Bandwidth consumption depends on target complexity, JavaScript-heavy pages, image-loaded listings, and failed retries, all of which burn data without returning results.
Datacenter proxies use per-IP or flat monthly billing, often with unlimited bandwidth. You run as many requests as your infrastructure supports without per-GB overages, making costs predictable at any volume.
The calculation most buyers overlook: cost-per-successful-request. A residential proxy succeeding 95% of the time frequently delivers a lower cost per usable data point than a datacenter proxy failing 50% on a protected target. Failed requests consume compute time and overhead while returning zero data. Teams running mixed workloads across protected and permissive targets benefit from comparing unlimited and pay-per-GB pricing to find the right structure.
Which Proxy Type Fits Your Use Case, Decision Framework
Target site security, geographic requirements, and operational scale determine which proxy type delivers the highest success rate per use case.
| Use Case | Recommended Proxy Type | Why |
| Web scraping Cloudflare-protected sites | Residential (rotating) | Real ISP IPs bypass anti-bot detection at 85–99% success |
| SEO rank tracking / SERP monitoring | Datacenter | Public search results need speed, not residential stealth |
| E-commerce price monitoring | Residential (rotating) | Retailer sites run aggressive bot detection and IP fingerprinting |
| Ad verification by geo-location | Residential (geo-targeted) | City-level IP precision verifies localized ad placements |
| Social media account management | Residential (sticky sessions) | Platforms flag datacenter ASN ranges and ban accounts |
| High-volume public API crawling | Datacenter | Permissive endpoints where speed and unlimited bandwidth matter most |
| Sneaker bots / limited releases | Residential | Drop sites deploy advanced fingerprinting and IP classification |
| Lead generation / competitor tracking | Hybrid (both) | Datacenter for public data, residential when anti-bot triggers |
Most advanced operations in 2026 run a hybrid proxy stack. Datacenter proxies handle 70–80% of request volume, public pages, APIs, SEO monitoring. Residential proxies across 195+ countries cover the 20–30% where anti-bot systems block server-hosted IPs. Starting datacenter and escalating to residential when CAPTCHA or 403 responses appear cuts total proxy spend compared to running residential for everything.
Three rules to decide fast:
- Target runs anti-bot detection (Cloudflare, PerimeterX, DataDome) → residential proxies
- Target is public and permissive → datacenter proxies for speed and scale
- Not sure about target security → start datacenter, switch to residential when blocked

Frequently Asked Questions
Are residential proxies always better than datacenter proxies?
Not for every use case. Residential proxies outperform on targets with anti-bot detection, but datacenter proxies deliver faster speeds and lower costs on permissive sites. Target security determines the right proxy type.
Why are residential proxies more expensive?
Residential IPs come from real ISP-assigned household connections that are scarce and require ethical sourcing from compensated users under GDPR/CCPA compliance. Datacenter IPs are generated in bulk from server infrastructure at far lower per-unit cost.
Do datacenter proxies work for web scraping?
Datacenter proxies scrape public, low-security sites at high speed. On platforms running Cloudflare, PerimeterX, or DataDome anti-bot detection, residential proxies achieve 85–99% success rates compared to 40–60% for datacenter IPs.
Which proxy type works for social media account management?
Residential proxies with sticky sessions protect account longevity on Instagram, TikTok, and LinkedIn. These platforms flag datacenter ASN ranges and ban detected accounts.
How do websites detect datacenter proxies?
Websites query ASN databases to check if an IP belongs to a consumer ISP or a hosting provider. Datacenter ASNs from AWS, OVH, and Hetzner are cataloged in detection databases, and anti-bot systems flag these IPs automatically with CAPTCHA, rate limits, and 403 blocks.
What is the difference between ISP proxies and residential proxies?
ISP proxies use static IPs registered to real Internet Service Providers but hosted on server infrastructure, combining residential-level IP reputation with datacenter speed. Residential proxies rotate through dynamic household IPs that change per request or session window.
Should I use both residential and datacenter proxies together?
A hybrid proxy stack is standard for advanced data operations. Datacenter proxies handle high-volume, low-security targets while residential proxies cover protected sites, cutting total proxy spend by 40–60% compared to residential-only setups.
Are residential proxies legal?
Residential proxies are legal when ethically sourced from consenting, compensated users and applied to lawful purposes like market research, price monitoring, and ad verification. PlainProxies sources all residential IPs through GDPR/CCPA-compliant agreements.
