ISP & Datacenter Proxies
Proxio ISP and Datacenter proxies are dedicated IPs delivered per order, each with its own host, port and credentials. They are built for flat-rate, unlimited-bandwidth workloads and do not use the Residential username-targeting grammar.
ISP and Datacenter proxies are dedicated IPs. You get a specific set of addresses that are yours for the life of the order, rather than drawing from a shared rotating pool. They are positioned for flat-rate, unlimited bandwidth: run them at full throughput without metering every gigabyte, which is Proxio's differentiator for high-volume work.
How these differ from Residential
Residential proxies are a pay-per-GB rotating pool behind one gateway with full username targeting. ISP and Datacenter proxies are the opposite model: fixed, dedicated IPs, each with its own connection details, and no username parameters.
How delivery works
Dedicated IPs are provisioned per order. Some are allocated instantly and some are set up manually, so right after purchase a service may show "delivery in progress" until its credentials appear. Once provisioning finishes, the connection details show up on the service and the proxies are ready to use.
Connection format
Each proxy is a standalone endpoint with its own host, port, username and password.
There is no shared gateway hostname and no -region- or -sessid- segments. A
dedicated proxy looks like this:
HOST:PORT:USERNAME:PASSWORDWritten as a proxy URL for most clients:
http://USERNAME:PASSWORD@HOST:PORTCopy the exact host, port, username and password from the dashboard. The values below are placeholders:
curl -x "http://USERNAME:PASSWORD@HOST:PORT" https://ipinfo.ioimport requests
proxy = "http://USERNAME:PASSWORD@HOST:PORT"
r = requests.get("https://ipinfo.io", proxies={"http": proxy, "https": proxy})
print(r.json())import { ProxyAgent } from "undici";
const proxyAuth = Buffer.from("USERNAME:PASSWORD").toString("base64");
const dispatcher = new ProxyAgent({
uri: "http://HOST:PORT",
token: `Basic ${proxyAuth}`,
});
const res = await fetch("https://ipinfo.io", { dispatcher });
console.log(await res.json());No username targeting on these proxies
Geo-targeting, sticky sessions and smart retry are Residential-only features
built into the gateway username. On a dedicated ISP or Datacenter IP, the location
is fixed by the IP itself. Appending -region- or -sessid- will not work. See
the Residential targeting reference for what the username grammar
covers.
Where to find your connection details
Open the ISP or Datacenter service in the dashboard. Its detail view lists the connection details for each delivered proxy along with ready-to-copy code examples, so you can paste a working snippet straight into your tooling.
Pricing and bandwidth
ISP and Datacenter proxies are sold on flat-rate, unlimited-bandwidth terms, with per-day duration options and discounts for longer durations. For current numbers, see the Proxio pricing page.
