Quick verdict: Rotating proxies pull a fresh IP from a pool of millions for each request — perfect for crawl and any task where the request count exceeds what one IP can survive. Static proxies stay on one IP indefinitely — perfect for account management, sticky sessions, and any flow where switching identity mid-session breaks things. Most serious stacks use both: rotating for the crawl tier, static for the account tier. Pricing differs too — rotating is usually metered per GB, static per IP per day or month.
What Each One Is
| Rotating Proxy | Static Proxy |
|---|
| IP behavior | Fresh IP per request (or per sticky session) | Same IP for the contract term |
| Pool size | 1M–130M IPs | One per account |
| Session model | Stateless or sticky (10 min–24 hr) | Permanent session |
| Best for | Crawling, SEO, ad verification, data collection | Social accounts, sneaker bots, banking, anything cookied |
| IP types available | Residential, datacenter, mobile (rotating mobile) | Static residential (ISP), static datacenter, dedicated mobile |
| Pricing model | Per GB transferred | Per IP per day or per month |
| Detection footprint | Each request fresh ⇒ lower per-IP signal | Identity continuity ⇒ can warm up like real user |
When Rotating Wins
- Web scraping at scale. 100k pages from one IP gets blocked; 100k pages spread over 100k IPs looks like 100k different users.
- Bypassing rate limits. Sites that limit per-IP requests don't see you exceeding the limit if every request comes from a different IP.
- SEO rank tracking. Querying Google or Bing from many IPs avoids the captcha that fires after ~50 queries from one IP.
- Ad verification. Verifying ad creatives from diverse geolocations and device profiles.
- Data collection where freshness matters. Each visit looks like a different user, so geo-personalized content shows you all variants.
Sticky sessions inside rotating pools (10 minutes, 1 hour, 24 hours of the same IP) bridge the gap for flows that need short-term consistency — checkout flows, multi-page forms, paginated scrapes.
When Static Wins
- Social media accounts. Instagram, TikTok, Twitter, Facebook expect one device + one IP per account. Rotating IPs on a single account triggers "suspicious login" flags every other day.
- Sneaker bots. Drops require persistent identity through queue + checkout. Lose the IP mid-checkout and you lose the slot.
- Banking, exchanges, brokerages. These platforms tie sessions tightly to IP; changes trigger re-authentication or fraud holds.
- Account warm-up. The whole point is "this device has logged in from this IP for 30 days" — rotating defeats the goal.
- SaaS dashboards. Most SaaS sessions break on IP change.
- Long-running sessions that exceed sticky max. If your task lives longer than the sticky-session limit (24 hours typical), use a static IP.
Pricing Models
Rotating — Pay per GB
Static — Pay per IP
Rotating economics favor high-volume burst use. 10GB through residential = $17.50–$27.50, after which you stop paying. Static economics favor steady all-month use. Static datacenter at $1.50/mo unlimited is genuinely free at scale relative to volume.
Rotation Models in Detail
- Per-request rotation. Every HTTP request gets a new IP. Maximum stealth, but breaks any flow that needs cookie continuity. Default for most residential providers.
- Sticky session (timed). Same IP for 10 min / 30 min / 1 hour / up to 24 hours, then a new IP. Configure via a session token in your proxy username (e.g.
session-abc123).
- Sticky session (per-target). Same IP for all requests to a given hostname; new IP for different hostnames. Useful for multi-target scrape where you want continuity per site.
- IP whitelist + rotation. Provider pins you to a smaller IP whitelist; rotation happens within that whitelist. Useful when target sites have allow-lists.
Types of Static
- Static Residential (ISP). Residential ASN, datacenter speed. Best static option for stealth. Most expensive.
- Static Datacenter. Server ASN, fastest, cheapest. Useful for any target that doesn't care about ASN.
- Dedicated Mobile. Real 4G/5G handset assigned to you. Best for mobile-fingerprinted platforms (Instagram, TikTok).
Sticky Sessions: The Best of Both?
Sticky sessions sit between rotating and static. You get the pool size of a rotating provider but with an IP that holds for a configurable window. Two common patterns:
- Crawl with 10-min sticky. Each "session" handles one site visit (homepage + a few sub-pages). New site = new session = new IP.
- Account checks with 1-hour sticky. Log in, do work, log out, get a new session for next account.
Sticky inside rotating doesn't replace static for true long-term identity flows — an account warmed for 30 days needs the same IP for 30 days, which only static delivers.
The Hybrid Stack
Real-world operators rarely pick one. Typical setup:
- Crawl tier — rotating residential ($1.75–$2.75/GB) for bulk scraping.
- Account tier — one static IP per account ($2–$3.90/day) for the social/financial/sneaker accounts.
- Verification tier — sticky residential for paginated scrapes that need short-term continuity.
Don't shove account flows through rotating — you'll waste hours on captchas and re-auth. Don't shove crawl through static — you'll get IP-banned in hours and have nothing to rotate to.
Quick Decision
| Use case | Pick |
|---|
| Scrape 1M pages this month | Rotating Residential |
| Manage 5 Instagram accounts | 5 Static Mobile (one per account) |
| Track SERP positions hourly | Rotating Residential |
| Log into a SaaS that re-auths on IP change | Static Residential |
| Multi-page checkout flow on a sneaker site | Static Mobile |
| One-off geo-check of competitor pricing | Rotating Residential (sticky 10 min) |
