Proxy networks power web scraping, SEO monitoring, and multi-account management across global markets. Success depends on understanding how these systems function, the mechanics of IP assignment, rotation strategies, session handling, and detection evasion.
Proxy networks route traffic through IP address pools, using rotation algorithms to swap IPs per request or at timed intervals. Session management maintains consistency for multi-step tasks. Detection systems identify proxies through IP reputation and behavioral patterns, but proper configuration defeats these mechanisms.
What Is a Proxy Network?
A proxy network consists of servers acting as intermediaries between users and target websites. When you send a request through a proxy, the server forwards that request using its own IP address. The target website sees the proxy IP, not your real address.
Modern proxy networks manage large pools of IP addresses through a central gateway. This gateway handles traffic distribution, assigns IPs based on rotation rules, and manages session persistence. The result: distributed traffic appearing to originate from thousands of different users.
IP Types in Proxy Networks
The source of proxy IP addresses determines detection risk, speed, and success rates on different platforms.
Datacenter Proxies
Datacenter IPs originate from cloud servers and commercial hosting facilities. They deliver the fastest speeds at the lowest costs. However, websites can identify datacenter IP ranges easily, making them unsuitable for heavily protected platforms.
Plain Proxies offers datacenter proxies with 15K+ IPs starting at €2.00/month, ideal for speed-critical tasks on less-protected sites.
Residential Proxies
Residential IPs come from real Internet Service Providers assigned to household connections. When traffic routes through residential proxies, websites see requests from legitimate consumer networks, the same connections their actual customers use.
This authenticity translates to significantly lower detection risk. Protected platforms like Amazon, eBay, and social networks rarely block residential IPs because doing so would affect real users.

ISP Proxies (Static Residential)
ISP proxies combine residential authenticity with datacenter stability. These static addresses maintain a consistent identity across sessions while appearing as legitimate ISP-assigned IPs. They work perfectly for account management, where the same IP must persist across multiple logins.
ISP proxies use static residential IPs and are priced by bandwidth, IP pool size, and concurrency mode. Unlimited bandwidth is available on select tiers starting from 100 IPs.
Mobile Proxies
Mobile IPs originate from cellular carriers operating 3G, 4G, and 5G mobile networks. Carriers naturally rotate these addresses among millions of devices, creating inherent trust. Websites rarely block mobile IPs because the same address might serve thousands of legitimate users throughout the day.
IPv6 Proxies
IPv6 represents the next generation of Internet addressing with a virtually unlimited pool of available addresses. As IPv4 exhaustion continues, more platforms support IPv6 connections. These proxies offer cost-effective high-volume operations on modern infrastructure.
IPv6 proxies provide unlimited address pools starting at €6.00/day for large-scale projects.
| IP Type | Source | Detection Risk | Best Application |
| Datacenter | Cloud servers | High | APIs, unprotected sites |
| Residential | Home ISPs | Low | Protected platforms |
| ISP/Static | ISP-assigned | Very Low | Account management |
| Mobile | Cellular carriers | Very Low | Maximum stealth |
| IPv6 | Next-gen addresses | Low | High-volume tasks |
How IP Rotation Works
IP rotation automatically changes the address used for outgoing requests. This distribution prevents any single IP from triggering rate limits or appearing suspicious through repeated access patterns.
Request-Based Rotation
Request-based rotation assigns a new IP for every single request sent through the proxy network. Each page load, API call, or data request originates from a different address. This maximizes anonymity and prevents pattern recognition across requests.
Use request-based rotation for large-scale scraping, price monitoring across thousands of products, and bulk data extraction where session continuity does not matter.
Time-Based Rotation
Time-based rotation changes IPs at fixed intervals, every minute, five minutes, or thirty minutes depending on configuration. This approach balances anonymity with moderate session continuity, allowing multiple requests from the same IP before switching.
Use time-based rotation for SEO monitoring, competitive research, and general automation where some consistency improves efficiency without requiring persistent sessions.
Intelligent Rotation
Intelligent rotation uses adaptive logic to determine when IP changes should occur. The system monitors website responses, CAPTCHAs, blocks, unusual delays, and rotates proactively when detection signals appear. This maximizes success rates through responsive behavior rather than fixed rules.
| Rotation Type | IP Change Trigger | Best Application |
| Per-Request | Every request | Bulk scraping |
| Time-Based | Fixed intervals | SEO, research |
| Intelligent | Detection signals | Protected platforms |
Session Management Explained
While rotation maximizes anonymity, some tasks require a consistent identity across multiple requests. Login flows need the same IP throughout authentication. Shopping carts reset if the IP changes mid-checkout. Multi-step forms fail with inconsistent addressing.
Sticky Sessions
Sticky sessions maintain the same IP address for a defined duration, typically between one and thirty minutes. The IP persists until the session expires or the task completes, enabling authenticated workflows and multi-step processes.
Account logins, e-commerce checkouts, form submissions, and any task where IP changes cause failure require sticky session configuration.
Rotating Sessions
Rotating sessions provide fresh IPs for each request without maintaining a persistent identity. This offers maximum anonymity and distribution across the IP pool, optimal for independent requests that do not require consistency.
Price monitoring, SERP tracking, and high-volume data collection without authentication benefit from rotating session configuration.
| Task Type | Recommended Session |
| Login flows | Sticky (10-30 min) |
| Cart/checkout | Sticky (10-30 min) |
| Price scraping | Rotating per-request |
| SERP tracking | Rotating per-request |
Detection Methods and Evasion
Websites deploy multiple detection layers to identify and block proxy traffic.
IP-Based Detection
Anti-bot systems maintain databases of known datacenter IP ranges and previously flagged addresses. ASN (Autonomous System Number) identification reveals whether traffic originates from commercial hosting rather than consumer ISPs. IP reputation scoring tracks historical behavior patterns.
Evasion requires residential or mobile IPs that fall outside datacenter databases and carry clean reputation histories.
Behavioral Analysis
Detection systems analyze request patterns, frequency, timing, navigation paths, and session duration. Bots typically request pages faster than humans can read them. They follow predictable paths. They skip resources that browsers load automatically.
Evasion requires realistic timing delays between requests and randomized patterns that mimic human browsing behavior.
Browser Fingerprinting
Advanced detection examines browser characteristics beyond IP addresses. Canvas rendering, WebGL signatures, installed fonts, and screen resolution create unique fingerprints. TLS and TCP connection patterns reveal whether traffic originates from real browsers or automated scripts.
Evasion requires a consistent fingerprint configuration paired with quality proxy infrastructure.
| Detection Method | Evasion Strategy |
| IP Blacklists | Residential/mobile IPs |
| Rate Limiting | IP rotation, timing delays |
| Behavioral Analysis | Human-like patterns |
| Fingerprinting | Consistent configuration |
