Rotating proxies automatically assign a new IP address for each request (or at configurable intervals). They're the backbone of web scraping, data collection, and any operation that needs to distribute traffic across thousands of IPs.
How Rotating Proxies Work
text
Your App → Proxy Gateway → IP Pool (100M+ IPs) → Target Website ↓ Request 1 → IP: 185.12.xx.xx Request 2 → IP: 91.234.xx.xx Request 3 → IP: 72.89.xx.xx (new IP every time)ZentisLabs gives you a pool of 100M+ residential IPs. When you send a request to basic.resi.zentislabs.com:12321, the gateway selects a fresh IP from the pool and routes your traffic through it.
Strategy 1: Per-Request Rotation
Every HTTP request gets a new IP. Best for scraping search results, collecting public data, and independent requests.
python
import requests
proxy = "http://USER:PASS@basic.resi.zentislabs.com:12321"proxies = {"http": proxy, "https": proxy}
# Each request: different IPfor i in range(100): r = requests.get("https://httpbin.org/ip", proxies=proxies) print(r.json()["origin"]) # New IP every timeStrategy 2: Sticky Sessions
Same IP maintained for the session lifetime you set (Basic: _lifetime-30m). Best for multi-step workflows, shopping carts, and account operations.
python
# Sticky session - same IP for 30 minutes (_lifetime-30m). Use the sticky line# exactly as generated in the dashboard or API: NODE_IP is its pinned gateway node.proxy = "http://USER:PASS_country-us_session-order789_lifetime-30m@NODE_IP:12321"proxies = {"http": proxy, "https": proxy}
session = requests.Session()session.proxies = proxies
# All use the same IPsession.get("https://shop.com/")session.get("https://shop.com/product/1")session.post("https://shop.com/cart/add", data={"id": 1})Strategy 3: Geo-Targeted Rotation
python
# Rotate within US IPs onlyproxy_us = "http://USER:PASS_country-us@basic.resi.zentislabs.com:12321"
# Rotate within German IPs onlyproxy_de = "http://USER:PASS_country-de@basic.resi.zentislabs.com:12321"
# Rotate within New York IPs only (the city follows its state)proxy_nyc = "http://USER:PASS_country-us_state-newyork-city-newyork@basic.resi.zentislabs.com:12321"Node.js Implementation
javascript
const axios = require('axios');const { HttpsProxyAgent } = require('https-proxy-agent');
const agent = new HttpsProxyAgent('http://USER:PASS@basic.resi.zentislabs.com:12321');
async function scrape(urls) { const results = []; for (const url of urls) { try { const response = await axios.get(url, { httpsAgent: agent, proxy: false, timeout: 15000, headers: { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) Chrome/122.0.0.0', } }); results.push({ url, status: response.status, data: response.data }); } catch (err) { results.push({ url, error: err.message }); } } return results;}Rotation Timing: How to Avoid Bans
| Target Type | Strategy | Delay |
|---|---|---|
| Public APIs | Per-request rotation | 0.5-1s |
| E-commerce sites | Per-request + headers | 1-3s |
| Social media | Sticky sessions | 2-5s |
| Cloudflare sites | Sticky + browser | 3-8s |
| Search engines | Geo-targeted + random | 5-15s |
The Golden Rules
- Don't hit the same domain faster than a human would - 2-5 second delays are usually safe
- Rotate User-Agents alongside IPs - a new IP with the same User-Agent is suspicious
- Use sticky sessions for stateful operations - changing IPs mid-flow triggers security alerts
- Respect robots.txt - it often reveals rate limit thresholds
- Monitor success rates - if they drop below 95%, slow down
Success Rate Optimization
python
import requestsimport timeimport random
PROXY = "http://USER:PASS@basic.resi.zentislabs.com:12321"proxies = {"http": PROXY, "https": PROXY}
def optimized_scrape(urls): session = requests.Session() session.proxies = proxies
user_agents = [ "Mozilla/5.0 (Windows NT 10.0; Win64; x64) Chrome/122.0.0.0 Safari/537.36", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) Safari/605.1.15", "Mozilla/5.0 (X11; Linux x86_64; rv:124.0) Firefox/124.0", ]
results = [] success = 0
for url in urls: session.headers.update({ "User-Agent": random.choice(user_agents), "Accept-Language": "en-US,en;q=0.9", }) try: r = session.get(url, timeout=15) if r.status_code == 200: success += 1 results.append(r.text) elif r.status_code == 429: time.sleep(10) except Exception: pass time.sleep(random.uniform(1.5, 4.0))
print(f"Success rate: {success}/{len(urls)} ({100*success/len(urls):.1f}%)") return resultsChoosing a Proxy Type for Rotation
| Proxy Type | Rotation | Best For |
|---|---|---|
| Residential | Per-request | General scraping, high stealth |
| ISP (Static) | Manual | Account management, SEO |
| Datacenter | Per-request | Speed-focused, bulk ops |
| Mobile (4G/5G) | Time-based | Social media, max stealth |
ZentisLabs bandwidth never expires - buy once, use whenever you want. No monthly resets. For most scraping tasks, residential rotating proxies offer the best balance of anonymity, success rate, and cost.
