Datacenter IPv4 proxies route your traffic through addresses owned by hosting companies, which makes them fast, stable and cheap, and also easy for protected websites to recognise. On BuyProxy they are billed per GB at $0.99/GB with no per-IP commitment, so you pay for the data you move instead of reserving addresses. This guide explains how per-GB datacenter billing works, what the proxies are good for, and when you should pay the same $0.99/GB for residential IPs instead.
What a Datacenter IPv4 Proxy Is
A datacenter proxy uses an IPv4 address that belongs to a cloud or hosting provider rather than a consumer internet connection. IPv4 is the older, 32-bit address format, and the supply is finite: ARIN's free pool of IPv4 space was depleted on 24 September 2015, which is why IPv4 addresses are traditionally rented one by one.
That scarcity is the origin of per-IP pricing in the proxy market: you pay a monthly fee for each address. Per-GB billing flips this around. Instead of reserving addresses, you draw from a pool and pay only for the bandwidth you use, which suits workloads where you do not care which exact IP you get.
How Per-GB Datacenter Billing Works
With BuyProxy's Datacenter IPv4 product you top up a balance in gigabytes, generate connection lines, and the balance drops as traffic flows. The key details:
- Rate: $0.99/GB, billed as you use it.
- Minimum top-up: $5.
- Credits never expire, so you can buy a small batch now and use it whenever.
- Bonus: top-ups of 100 GB or more add 10% extra.
- Separate balance: each proxy type has its own balance, so a datacenter top-up does not draw from your residential GB. Plans credit their monthly GB to Core Residential only.
Full pricing across every type is on the pricing page, and the cost-per-volume math is in our residential proxy pricing guide.
The Honest Pricing Observation
Datacenter proxies are traditionally the cheap option, but on BuyProxy Datacenter IPv4 costs $0.99/GB, exactly the same as Core Residential. That changes the decision. Because the price is identical, cost is not a reason to pick datacenter for any target that detects hosting ranges. You would pay the same and get a much higher block rate.
The cheaper datacenter option is IPv6 at $0.29/GB, covered in what is an IPv6 proxy. So the real choice is between datacenter IPv4 for IPv4-only, unprotected targets and IPv6 for the lowest-cost IPv6-friendly traffic.
What Datacenter IPv4 Proxies Are Good For
Datacenter IPs sit on high-bandwidth hosting infrastructure, so they tend to be quick and consistent. They fit jobs where the target does not care who is asking:
- Public data and open APIs that do not block hosting ranges.
- Checking your own sites from different network locations, such as uptime or link checks.
- Bulk fetching of non-sensitive pages where speed matters more than blending in.
- Internal tooling and QA that needs IPs other than your office address.
If a job sits in this list, datacenter IPv4 is a sensible choice. For anything account-based or behind bot protection, move up.
Where Datacenter Proxies Fail
Anti-bot systems classify addresses by the network that owns them. Hosting and cloud ranges are public, so a request from a datacenter ASN starts with a lower trust score before any behavioural check runs. Protected e-commerce, search, social and ticketing sites commonly challenge or block that traffic. If you hit repeated 403s or CAPTCHAs on a target, that is the classic sign, and our error code guide explains how to confirm it.
The residential vs datacenter comparison goes deeper on this trade-off, and ISP rotating proxies sit in the middle: datacenter-hosted but registered to an ISP, at $1.49/GB.
Datacenter IPv4 vs the Alternatives
| Type | Price/GB | Detection risk | Choose it when |
|---|---|---|---|
| Datacenter IPv4 | $0.99 | High on protected sites | Target is IPv4-only and does not block hosting ranges |
| IPv6 | $0.29 | High, plus IPv6 compatibility gaps | Target accepts IPv6 and cost per GB is the priority |
| ISP Rotating | $1.49 | Medium | You want speed with fewer datacenter flags |
| Core Residential | $0.99 | Low | Target blocks hosting ranges |
How to Test Whether a Target Accepts Datacenter IPs
Before you spend a large budget, run a small test. Generate a line from the dashboard or the API, then fetch the target through it. A simple check is to compare the status code and body through the proxy against a direct request:
curl -s -o /dev/null -w "%{http_code}\n" -x "http://USER:PASS@HOST:PORT" https://example.com/
curl -s -o /dev/null -w "%{http_code}\n" https://example.com/If the proxied request returns a 403, a CAPTCHA page or a much smaller body than the direct request, the target is treating datacenter traffic differently. Our IP checker shows how an address is classified, and the proxy testing guide has a script that repeats this at scale and records success rate and timing.

Frequently Asked Questions
Q: What is the difference between datacenter and residential proxies?
Datacenter proxies use IPs owned by hosting companies, while residential proxies use IPs assigned to real home connections. Datacenter IPs are fast and easy to identify, residential IPs are harder for protected sites to block.
Q: How much do datacenter IPv4 proxies cost on BuyProxy?
$0.99 per GB, with a $5 minimum top-up and credits that never expire. That is the same rate as Core Residential, so choose between them by how strictly your target blocks automation, not by price.
Q: Do I pay per IP or per GB?
Per GB. There is no per-IP commitment: you top up a balance and it is drawn down as traffic flows through the proxy.
Q: Are datacenter proxies faster than residential proxies?
Usually, because they run on hosting-grade infrastructure rather than consumer connections. Real speed depends on the target and the route, so measure your own workload before you decide.
Q: Will datacenter proxies get blocked?
On protected sites, often. Anti-bot systems maintain lists of hosting ranges and challenge traffic from them by default. On unprotected targets they work fine.
Summary
Datacenter IPv4 proxies are fast, stable and billed per GB at $0.99 with no per-IP commitment, but they are easy to detect. Because that price equals Core Residential on BuyProxy, use datacenter IPv4 only for unprotected, IPv4-only targets, pick IPv6 at $0.29/GB when cost is the priority, and choose residential for anything that blocks hosting ranges.
