Basics

Datacenter proxies run on servers in data centers instead of real consumer devices. That makes them much faster and cheaper than residential proxies — they come with unlimited bandwidth and are billed per IP, not per GB. The trade-off: some sites can tell they’re not home connections, so heavily protected targets may block them.

This is a developer guide: For easy and fast proxy creation head over to your Datacenter dashboard and create proxies there. Here is the dashboard link: https://app.roundproxies.com/dashboard/datacenter

When to use them

Datacenter proxies are the right choice when speed and cost matter more than looking like a regular home user:

Scraping sites with little or no bot protection
SEO and rank tracking
Ad verification
Load testing your own services
Accessing geo-restricted content that doesn’t block datacenter IPs

If your target site blocks datacenter IPs (frequent 403 responses, captchas on every request), switch to Residential Proxies instead.

Proxy Format

Unlike residential proxies, datacenter proxies are dedicated — you get a fixed list of IPs that belong to you for the length of your plan. The dashboard gives you each proxy in this format:

IP:PORT:USERNAME:PASSWORD

Components Breakdown

Component	Description	Example
IP	Your dedicated proxy IP	`192.0.2.10`
Port	Connection port	`8000`
Username	Your proxy username	`YOUR_USERNAME`
Password	Authentication password	`YOUR_PASSWORD`

Because the IPs are dedicated, there’s no session parameter — the IP never changes unless you replace it from the dashboard.

Supported Protocols

All datacenter proxies support HTTP, HTTPS, and SOCKS5 on the same endpoint. Use whichever your tooling expects.

Example Request

import requests

proxies = {
    'http': 'http://{USERNAME}:{PASSWORD}@{PROXY_IP}:{PORT}',
    'https': 'http://{USERNAME}:{PASSWORD}@{PROXY_IP}:{PORT}'
}

response = requests.get('https://api.ipify.org?format=json', proxies=proxies)
print(response.json())

curl -x "http://{USERNAME}:{PASSWORD}@{PROXY_IP}:{PORT}" \
  https://api.ipify.org?format=json

The response should return your proxy’s IP, confirming the connection works.

Tips

Spread requests across all your IPs instead of hammering one — even dedicated IPs get rate-limited by target sites.
If an IP gets banned by a target, replace it from the dashboard rather than retrying against the ban.
You can skip credentials entirely by whitelisting your server’s IP — see Authentication.
