What are datacenter proxies?
Datacenter proxies are proxies whose IP addresses belong to cloud, hosting or colocation providers rather than consumer internet providers. The proxy software runs on servers in data centres, connected to fast, high-capacity networks. When you use one, websites see an IP registered to a company like a hosting provider or the proxy provider itself, not a household.
They're the original commercial proxy and still the workhorse of the industry: fast, inexpensive, reliable and available in huge quantities. Their one big weakness is that websites can tell they're datacenter IPs.
How websites recognise datacenter IPs
IP addresses are registered to organisations in public databases. Each IP belongs to an ASN (Autonomous System Number) with a name and a type. Commercial IP intelligence services classify ASNs as hosting, ISP, mobile, business and so on. When your request arrives from an IP whose ASN is classified as hosting, bot protection systems know it's very unlikely to be an ordinary person on a home connection.
That doesn't mean every site blocks datacenter IPs. Most websites don't use aggressive bot protection. But big retailers, social networks, search engines, ticketing and sneaker sites usually challenge or block them.
Advantages
- Speed. Datacenter proxies run on gigabit-class connections with low latency. They're the fastest proxy type.
- Price. Datacenter IPs are cheap to provide, so you pay a fraction of residential pricing. See cheap datacenter proxies.
- Unlimited bandwidth. Many plans don't meter data at all.
- Stability. The IP is always online. No devices disappearing mid-session.
- Availability. Easy to buy hundreds or thousands at once.
Disadvantages
- Easier to detect and block on protected sites.
- Subnet bans. Datacenter IPs are often sold in contiguous blocks; if a site bans the /24, you lose them all.
- Limited geographic depth. Locations are tied to where data centres are, typically major cities.
- Shared reputation. Ranges previously used for spam or abuse carry that history.
Types of datacenter proxies
| Type | Description | Best for |
|---|---|---|
| Dedicated | IPs used only by you | Consistent, controllable performance |
| Shared | IPs shared with other customers | Lowest cost, light tasks |
| Semi-dedicated | Shared by 2 to 3 customers | Middle ground |
| Rotating datacenter | Gateway that rotates through a datacenter pool | Large-scale scraping of tolerant sites |
| IPv6 datacenter | Abundant IPv6 addresses | IPv6-ready targets. See IPv6 proxies |
When datacenter proxies are the right choice
- Scraping websites without strong bot protection, which is the majority of the web.
- Public APIs, government data, news sites, many B2B sites.
- SEO tools on search engines that tolerate them (increasingly rare for Google; see SEO proxies).
- Sneaker monitors and some smaller Shopify stores.
- Speed-critical tasks where stability matters more than trust.
- Testing and development.
- Bandwidth-heavy tasks where per-GB residential pricing would be prohibitive.
When to choose something else
If your target uses Cloudflare Bot Management, Akamai, Datadome, HUMAN or Kasada at aggressive settings, or if you need accounts to look like real consumers, move to ISP proxies or residential proxies. Our comparison residential vs datacenter proxies explains the trade-off in detail.
Proxy tip: Geonode is one of the providers that sells all of the main types under one account: rotating and sticky residential, static ISP proxies with unmetered bandwidth, and rotating datacenter proxies. That makes it easy to test which type a target actually needs. More in Geonode datacenter proxies.
Pricing
Typical market ranges at the time of writing:
- Shared datacenter: often a few cents per IP per month, or bundles of hundreds of IPs for a few dollars.
- Dedicated datacenter: roughly $0.50 to $2.50 per IP per month, falling with volume.
- Rotating datacenter: priced per GB (often well under $1/GB) or per port/thread.
How to choose a datacenter proxy provider
- Subnet diversity. Ask how many distinct /24 subnets your IPs will span. More is better.
- ASN diversity. IPs under several different hosting ASNs are more resilient.
- Locations. Do they have IPs where your targets' servers are?
- Replacement policy. Can you swap IPs that are banned on your target?
- Bandwidth and threads. Unlimited, or capped?
- Protocols. HTTP(S) and SOCKS5.
- Trial or refund window to test on your targets.

Getting the most from datacenter proxies
- Send realistic headers and a consistent user agent.
- Spread requests across subnets, not just IPs.
- Keep per-IP request rates modest. See rate limiting and proxies.
- Use an HTTP client with a browser-like TLS fingerprint for sites that check it.
- Monitor block rates per subnet and retire bad ones.
Datacenter proxy setups that work well
The polite crawler
A few dozen dedicated datacenter IPs across several subnets, realistic headers, per-domain concurrency limits, and a backoff policy. This simple setup handles a huge range of public sites at very low cost.
The waterfall first tier
All requests start on datacenter proxies; failures escalate to residential. Many targets never need escalation, so most traffic stays cheap. See proxy rotation strategies.
The speed-critical monitor
Dedicated datacenter IPs near the target for monitoring prices, stock or availability with minimal latency. See sneaker monitor proxies.
Checking a datacenter proxy's network
curl -s -x http://USER:PASS@203.0.113.21:8080 https://ipinfo.io/jsonThe org field shows the hosting network. Spreading your IPs across several different hosting ASNs makes you more resilient to ASN-level blocks.
Datacenter proxies and TLS fingerprints
Many "datacenter proxies are blocked" experiences are really "Python requests is blocked". Bot protection often checks TLS fingerprints, and default HTTP library fingerprints differ from browsers. Combining datacenter IPs with a browser-like TLS client, or a real browser, can turn a blocked target into a working one. See browser fingerprinting and proxies.
IPv6 datacenter options
For targets that support IPv6, IPv6 datacenter proxies offer enormous numbers of addresses at very low cost, with subnet-level caveats. See IPv6 proxies.
Why cloud IPs are the easiest to spot
Not all datacenter IPs look the same to a website. The big cloud platforms publish their address ranges in machine-readable files so customers can configure firewalls: AWS publishes its IP ranges, Google publishes cloud.json, and Microsoft publishes Azure service tags. Any website can download those lists and treat traffic from them differently, and many bot management systems do exactly that.
In practice:
- Proxies running on AWS, Google Cloud or Azure are the easiest to identify. They're fine for your own infrastructure, public APIs and lenient sites, but a poor choice for anything with bot protection.
- Proxies on smaller hosting and colocation networks are still identifiable through ASN data, but less universally flagged, which is why proxy sellers favour them.
- Your own scraper on a cloud server sends traffic from a cloud IP unless you route it through a proxy. That's a common reason a script that works on a laptop fails as soon as it's deployed.
You can check where any datacenter IP lives with a whois or ASN lookup; see how proxy providers source their IPs. If you want to run your own exit, see self-hosted Squid proxy. If you need many IPs, rotating datacenter proxies and cheap datacenter proxies are the usual next step.
FAQ
Are datacenter proxies bad?
No. They're the best value proxies for most of the web. They're just not suitable for heavily protected sites.
Are datacenter proxies anonymous?
They hide your IP and add no headers, but websites can tell the IP belongs to a datacenter.
Can datacenter proxies be used for sneakers?
Only on lenient sites and for monitors. See datacenter proxies for sneakers.
Editorial note: Proxy providers change their pools, features and prices often, so treat any figures here as typical ranges at the time of writing and confirm current terms with the provider before you buy.
