Basics

ISP proxies sit between our two other proxy types: the IPs are registered with real internet providers, so target sites see them as home connections, but they’re hosted on datacenter hardware, so you get datacenter speed and uptime. They’re also called static residential proxies — you get dedicated IPs that don’t rotate, with unlimited bandwidth.

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

When to use them

Pick ISP proxies when you need one IP to stay the same and look residential:

Managing accounts that flag logins from changing or datacenter IPs
Checkout and purchase flows on protected shops (sneaker sites, ticketing)
Long scraping sessions against targets that block datacenter IPs
Anything where a rotating residential IP would log you out mid-session

Rule of thumb across the three products: datacenter for speed on easy targets, residential for rotation across a huge pool, ISP for a stable IP that passes as residential.

Proxy Format

Like datacenter proxies, ISP proxies are dedicated — the dashboard gives you a fixed list of IPs in this format:

IP:PORT:USERNAME:PASSWORD

Components Breakdown

Component	Description	Example
IP	Your dedicated static residential IP	`198.51.100.7`
Port	Connection port	`8000`
Username	Your proxy username	`YOUR_USERNAME`
Password	Authentication password	`YOUR_PASSWORD`

There’s no session parameter and no rotation — the IP is yours and stays the same for the length of your plan.

Authentication

Username/password and IP whitelisting both work. See Authentication for setup details.

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

Stick to one IP per account when doing account management — that’s the whole point of a static IP.
Bandwidth is unlimited, but target sites still rate-limit individual IPs. Spread heavy scraping across several IPs.
If an IP gets banned by a target, replace it from the dashboard. Since ISP IPs look residential, bans are rarer than on datacenter IPs but not impossible.
