What is Datacenter Proxy?

Datacenter proxies are IP addresses assigned to commercial cloud hosting providers like AWS, DigitalOcean, or Hetzner rather than residential ISPs. Because they run on bare metal or virtual machines with gigabit uplinks, they offer the highest throughput and lowest latency of any proxy class. However, their ASN ownership is public record, making them trivial for anti-bot systems to identify and block on high-security targets.

Speed over
stealth.

The workhorse of web scraping. When the target doesn't care who you are, datacenter IPs give you the cheapest, fastest path to the data.

TL;DR

Datacenter proxies route your traffic through commercial servers. They are incredibly fast and cost a fraction of residential IPs, but their ASN (Autonomous System Number) immediately flags them as non-human. They are perfect for surface web scraping, API polling, and targets with low anti-bot friction.

01Definition & structure
A datacenter proxy is an IP address provided by a commercial cloud hosting company or data center, rather than an Internet Service Provider (ISP). When you route traffic through one, the target server sees the request originating from a server farm (e.g., AWS, Google Cloud, Linode) instead of a residential home. They are characterized by high bandwidth, low latency, and extremely low cost per gigabyte.
02The ASN problem
Every IP address belongs to an Autonomous System Number (ASN). The ASN registry is public. Anti-bot systems like Cloudflare and DataDome maintain databases of commercial ASNs. If a request comes from an Amazon AWS ASN, the target knows immediately that it is not a human browsing on a laptop. This makes datacenter proxies highly susceptible to blanket IP bans on heavily protected sites.
03Dedicated vs. Shared
Datacenter proxies come in two flavors. Shared proxies are pooled among hundreds of users; they are incredibly cheap but often pre-banned on major sites because someone else abused them. Dedicated proxies give you exclusive use of the IP. While slightly more expensive, they offer predictable performance and a clean reputation history, making them the standard for production scraping pipelines.
04How DataFlirt handles it
We treat datacenter proxies as our first line of offense. Our routing engine maintains a massive pool of dedicated datacenter IPs. For every new target, we attempt extraction using this tier first to minimize client costs. If the target's WAF blocks the ASN, our system automatically tags the domain and seamlessly escalates the request to our ISP or residential proxy tiers without dropping the pipeline job.
05Did you know: IP warming
You can't just buy 10,000 datacenter IPs and immediately blast a target with them. Many WAFs track the "age" and historical traffic volume of an IP. A completely silent IP that suddenly sends 50 requests per second is an obvious anomaly. Production pipelines require "IP warming"—gradually increasing the request rate over days to build a credible traffic history before hitting peak concurrency.
// 03 — the economics

Why use
datacenter IPs?

Datacenter proxies win on unit economics and raw speed. DataFlirt's routing engine defaults to datacenter IPs for any target where the block rate remains below our threshold.

Cost per GB = Cdc ≈ Cres / 20
Datacenter bandwidth is practically free compared to residential routing. Industry average pricing
Effective Latency = Leff = Ltarget + Lproxy_hop
Often < 50ms overhead, vs 500ms+ for residential peer-to-peer networks. DataFlirt telemetry
Block Rate Threshold = Brate = 403s / total_requests
If B > 0.05, we automatically escalate the session to ISP or residential pools. DataFlirt proxy waterfall logic

Routing through
a datacenter node.

A standard HTTP GET request routed through a dedicated US-East datacenter proxy, hitting a target with basic rate-limiting but no strict ASN blocks.

How targets
spot datacenter IPs.

Datacenter IPs don't hide what they are. Anti-bot systems use public BGP routing data to classify traffic before a single byte of HTTP is inspected.

DataFlirt's proxy waterfall always attempts to use datacenter IPs first. We maintain a proprietary pool of over 2 million dedicated datacenter IPs across 400+ ASNs. If a target returns a CAPTCHA or a 403, our engine automatically retries the request through an ISP or residential node. This keeps your pipeline costs as low as mathematically possible without sacrificing success rates.

About datacenter proxies, their limitations, legality, and how DataFlirt integrates them into high-volume pipelines.

Ask us directly →
What is the difference between a datacenter and a residential proxy? +
Datacenter proxies are hosted on commercial servers (like AWS or Hetzner). They are fast, cheap, and their IP addresses are publicly known to belong to data centers. Residential proxies route traffic through real consumer devices (like a home Wi-Fi router). They are slower and more expensive, but they look like legitimate human traffic to anti-bot systems.
Are datacenter proxies legal to use? +
Yes. Using a datacenter proxy is simply routing your traffic through an intermediary server. It is a standard network engineering practice. However, legality depends on what you are doing with the proxy. Scraping public data is generally lawful, but using proxies to bypass authentication, commit fraud, or launch DDoS attacks is illegal regardless of the proxy type.
Can I use datacenter proxies to scrape Google or Amazon? +
Generally, no. Tier-1 targets like Google, Amazon, and LinkedIn use aggressive ASN blocking. If you hit them with an AWS or DigitalOcean IP, you will receive a CAPTCHA or a hard block almost immediately. For these targets, DataFlirt automatically routes requests through residential or high-quality ISP proxy pools.
What is the difference between shared and dedicated datacenter proxies? +
Shared proxies are used by multiple customers simultaneously. They are cheaper but carry a high risk of being "burned" (banned) by other users' bad behavior. Dedicated proxies are assigned exclusively to you. DataFlirt uses dedicated datacenter IPs to ensure our clients' pipelines aren't affected by noisy neighbors.
How does DataFlirt handle IP bans on datacenter nodes? +
We monitor the block rate of every IP in our pool in real-time. If a dedicated datacenter IP starts returning 403s or CAPTCHAs above a 5% threshold, our routing engine automatically rotates it out of the active pool, places it in a cooldown queue, and assigns a fresh IP from a different subnet.
What kind of throughput can I expect from a datacenter proxy? +
Massive. Because they sit on commercial fiber backbones, a single datacenter proxy can easily handle hundreds of concurrent connections and gigabit speeds. The bottleneck is almost never the proxy itself; it is the target server's rate limits or your own scraper's parsing speed.
