Datacenter vs residential vs mobile proxies: which to use (2026)
Three kinds of proxy IP, three cost structures, three ban profiles. The choice between them is a risk/reward calculation that changes depending on what you're scraping and how hard the target fights back.

Most proxy comparisons read like a glossary. Here are the three types, here are the definitions, good luck. That's not how the decision actually works. You're choosing between speed and stealth, between flat-rate and per-GB, between IPs that get flagged instantly and IPs that are almost impossible to block. The tradeoff shifts with every target.
Here's how I think about it after running scraping infrastructure against everything from open REST APIs to Cloudflare-gated storefronts.
Datacenter proxies
Datacenter IPs come from hosting providers. AWS, GCP, OVH, Hetzner, DigitalOcean. They sit in known IP ranges that every anti-bot vendor has cataloged for years.
The upside: fast (low latency, high bandwidth), cheap (flat-rate or pennies per IP), and you can spin up hundreds in minutes. The downside: on any target running real bot detection, they're dead on arrival.
Anti-bot systems check your IP against databases of known datacenter ASNs before they inspect anything else. Cloudflare, DataDome, Akamai, PerimeterX — they all do it. Your IP resolves to an ASN owned by Amazon, and the trust score drops before your TLS handshake even finishes.
That doesn't make datacenter proxies useless. They're great for targets that don't run anti-bot at all (plenty of sites don't), for API endpoints that authenticate by key rather than IP reputation, and for raw throughput on cooperative sources. I still reach for them in those cases. The cost per request is basically zero compared to residential, and the bandwidth is better.
But the moment you see 403s, challenges, or CAPTCHAs, rotating through more datacenter IPs won't help. More flagged IPs is still flagged IPs.
Residential proxies
Residential IPs are assigned by ISPs to real home connections. Route through one and the target sees Comcast, Deutsche Telekom, BT, whatever the local carrier is. That's the whole value: the IP looks like a regular person browsing from their apartment.
This is the default choice for any target behind serious bot detection. A residential IP paired with a proper browser fingerprint and sane request timing clears most defenses. We go deeper on picking a pool in the residential proxy guide.
The cost model is different from datacenter. You pay per gigabyte of traffic, not per IP. Depending on the provider and the geo you need, that runs anywhere from $2/GB to $15/GB. On data-heavy scrapes (images, full page renders, JavaScript-heavy SPAs), the bandwidth bill adds up fast. It's the single biggest variable cost in most scraping operations, and it's the one I watch closest.
The trap people fall into: thinking residential IPs are a silver bullet. They aren't. A
residential IP paired with a raw Python requests handshake still looks wrong,
because the TLS fingerprint screams "script" while the IP says "home user." That
incoherence is what modern detectors score. The IP buys you the benefit of the doubt. A
bad fingerprint spends it immediately.
A residential pool that doesn't burn itself
The proxy provider matters as much as the proxy type. A pool with stale, overused IPs performs worse than a smaller pool of genuinely clean residential addresses.
Mobile proxies
Mobile IPs are assigned by cellular carriers (AT&T, T-Mobile, Vodafone) and shared across thousands of devices via carrier-grade NAT. That sharing is what makes them special. When thousands of real phones share the same IP pool, blocking any single address in that pool means blocking real customers. Anti-bot vendors know this, and they won't do it.
That makes mobile proxies the hardest to block and the most expensive to buy. Expect $20/GB to $50/GB or higher, with lower throughput (you're routing through a cellular backhaul, not a datacenter backbone).
I think of mobile as the escalation option. The cost makes it impractical for large crawls. You're not pulling 50GB of product data through mobile proxies at $30/GB. But for high-value, low-volume targets (a handful of pages behind very aggressive detection, session-based flows on banking or travel sites, targets that actively hunt residential proxy ranges), mobile IPs have the highest success rate per request.
One thing to check: some "mobile" providers sell rebranded residential IPs. Look up the exit IP's ASN on a service like ipinfo.io. If it maps to a consumer ISP instead of a mobile carrier, you're paying mobile prices for residential quality. The whole point of mobile is the CGNAT pool that makes blocking impractical. Without that, you've just got an expensive residential IP.
Proxy management is the boring part
Choosing the right proxy tier, rotating correctly, matching fingerprints to the exit IP's geo, watching bandwidth spend, swapping providers when pools degrade. Hire a Clawd handles the whole proxy stack as part of the scraping agent, so you get clean data without managing the plumbing.

This isn't a proxy type. It's a session mode, and getting it wrong burns IPs or breaks scrapes regardless of which tier you're on.
Rotating gives you a fresh IP every request (or every N seconds). Use it for broad crawls, independent page fetches, search results, catalog pages. Each request looks like a different user, which spreads the fingerprint load and makes pattern detection harder.
Sticky holds one IP for a configurable duration (5 minutes, 10 minutes, 30 minutes). Use it for login flows, multi-page checkouts, any scrape that needs cookies or session state to persist across requests. If your IP changes mid-session, the server sees a session cookie arriving from a new location. Strong signal.
The common mistake: running everything on sticky because it "feels safer." It's not. Sticky ties you to one IP for the full window, so if that IP gets flagged, every request in the window fails. Rotating spreads the risk. Stick to sticky only when the target requires session continuity.
In Python with most proxy providers, the switch is a gateway URL change:
proxy_rotating = "http://user:pass@gate.provider.com:10000"
proxy_sticky = "http://user-session-abc123:pass@gate.provider.com:10001"
import httpx
# Broad crawl: rotate
for url in catalog_urls:
r = httpx.get(url, proxy=proxy_rotating)
# Login flow: stick
with httpx.Client(proxy=proxy_sticky) as client:
client.post("https://example.com/login", data=creds)
r = client.get("https://example.com/account")Decision table by target type
The right proxy depends on what you're hitting. Here's the short version:
| Target | Proxy type | Session mode | Why |
|---|---|---|---|
| Public API, no anti-bot | Datacenter | Rotating | Cheapest, fastest. No detection to dodge. |
| E-commerce (Cloudflare/DataDome) | Residential | Rotating | IP reputation check is the first gate. Residential passes it. |
| Login-gated site | Residential | Sticky | Session cookies must stay on the same IP. |
| Aggressive anti-bot (Akamai strict, custom WAF) | Residential, escalate to mobile | Rotating or sticky by flow | Try residential first. If ban rate stays high, mobile IPs survive where residential won't. |
| Banking / travel / high-value session | Mobile | Sticky | Highest trust score. Worth the cost for a handful of pages. |
| Geo-restricted content | Residential (targeted country) | Rotating | Residential with country targeting passes geo checks. Datacenter IPs often resolve to the wrong region. |
A hybrid approach works too, and it's what I'd recommend for any job with mixed targets. Route easy pages through datacenter, protected pages through residential, and keep mobile in reserve for the targets that eat through residential pools. Match the cost to the difficulty.
The mistakes that burn clean IPs
This matters more than the proxy choice itself. A clean residential pool can get flagged fast if you handle it wrong.
Hammering one target from one IP. Residential IPs have a reputation score, and it's not static. Hit a target 200 times in 10 minutes from the same IP and the score drops. The IP was clean when you started. It won't be when you're done.
Mismatched fingerprints. I've said this twice already, but it bears
repeating because it's the number-one reason residential IPs "don't work." A residential
IP paired with a default Python TLS handshake or a headless Chrome leaking
navigator.webdriver = true is incoherent. The IP says home user, the
fingerprint says bot. Fix the fingerprint with something like
Camoufox or
curl_cffi before blaming the proxy provider.
Wrong geo. You're scraping a UK retailer through a residential IP in
Brazil. The request looks weird because it is weird. Most providers let you target by
country, sometimes city. Use it. And make sure the browser's timezone and locale match the
exit IP's location (Camoufox's geoip=True handles this automatically).
Ignoring bandwidth cost until the invoice. Residential is per-GB. A scrape that renders full JavaScript pages (including all the ad trackers, analytics scripts, and third-party fonts) can burn 3-5x the bandwidth of a targeted API call. If you only want the product JSON, don't render the whole page. Block unnecessary resource types at the browser level:
await page.route("**/*.{png,jpg,gif,css,woff2}", lambda route: route.abort())
await page.goto("https://example.com/product/123")Not rotating when you should be. Broad crawl on a sticky session means one IP takes all the heat instead of distributing across the pool. Rotate for independent requests. Always.

Can I mix proxy types in one scrape?
Yes, and you should for cost efficiency. Route unprotected endpoints through datacenter proxies, protected pages through residential, and keep mobile in reserve for the targets that flag residential pools. Match the proxy tier to the target difficulty, not to convenience.
How do I verify my "residential" proxies are actually residential?
Look up the exit IP's ASN on ipinfo.io or bgp.tools. It should resolve to a consumer ISP (Comcast, BT, Vodafone), not a hosting provider. Some providers mix datacenter IPs into "residential" pools to stretch inventory. If your residential IP maps to OVH or Hetzner, you're paying residential prices for datacenter quality.
Are residential proxies worth the per-GB cost?
Depends entirely on the value of the data. If you're pulling pricing intelligence that drives meaningful revenue decisions, a few hundred dollars a month in proxy costs is noise. If you're scraping public RSS feeds, it's a waste. Match the proxy tier to the target's defenses and the value of what you're extracting. That's the whole calculus.
What about ISP proxies (static residential)?
ISP proxies are datacenter-hosted IPs registered under a residential ASN. They combine datacenter speed with a residential-looking ASN, and they don't rotate (you keep the same IP). Good for long sessions where you need stability and decent trust scores. The catch: anti-bot vendors are getting better at identifying these. They show up as residential on a basic ASN check, but the hosting pattern (always-on, high volume from one IP) can still get them flagged on aggressive targets. Think of them as a middle tier between pure datacenter and true residential.
