What Is an ISP Proxy?

What Exactly Is an ISP Proxy?

An ISP proxy is a fixed IP address sourced from a real home broadband network.

Think of it this way: it's your home internet connection routed through a proxy server—so websites see a genuine residential IP from your ISP, not your actual location.

What does ISP stand for?

ISP = Internet Service Provider. That's your cable company, telecom, or fiber provider. In the US, think Comcast, AT&T, or Spectrum. In the UK, BT or Virgin Media. These are the companies that provide internet to homes and businesses.

So an ISP proxy's IP address is traceable to a real geographic location and ISP—not some anonymous data center.

How Do ISP Proxies Work?

Here's what happens when you connect through an ISP proxy:

1. Real Residential IP: The IP comes from an actual home broadband network, not a server farm

2. Fixed Address: The IP stays the same throughout your subscription—no random rotation

3. Proxy Routing: Your requests go through the proxy server before reaching the target website

4. Authentic Attribution: The website sees an IP tied to a real ISP in a specific city—like a normal household browsing

This setup makes ISP proxies incredibly effective for tasks that require high trust levels from websites.

Key Features of ISP Proxies

Where Do ISP Proxies Shine?

1. Multi-Store E-Commerce Operations

Platforms like Amazon, eBay, and Shopify are strict about account associations. Each store needs its own IP address, network environment, and browser fingerprint.

ISP proxies provide fixed IPs that look like genuine home users—dramatically reducing the risk of account linking.

2. Social Media Account Management

When running multiple Facebook, Instagram, TikTok, or Twitter accounts, each needs its own environment.

ISP proxies are ideal for social accounts that need to stay logged in long-term without IP changes triggering security alerts.

3. High-Value Account Registration & Maintenance

For accounts worth serious money—Google Voice, PayPal, seller accounts—stability is non-negotiable.

A fixed IP ensures these accounts always access from "the same home network," minimizing the chance of triggering risk controls.

4. Ad Verification & Campaign Testing

Marketers need to see ads from different regional perspectives.

ISP proxies can be tied to specific locations, letting you verify how ads display in different markets.

5. Price Monitoring & Competitive Intelligence

E-commerce professionals need to track competitor pricing, inventory, and promotions continuously.

The fixed IP makes ISP proxies great for long-running monitoring tasks that require consistent access.

6. Brand Protection & Infringement Detection

Brands need ongoing monitoring for counterfeit products and trademark violations across platforms.

ISP proxies let you see the web from a local user's perspective in your target markets—making it easier to spot issues and take action.

ISP Proxy vs. Residential Proxy: What's the Difference?

Here's where things get confusing for many people. The simple answer: ISP proxies are a type of residential proxy.

Types of Residential Proxies

Residential proxies come in two flavors based on whether the IP changes:

The Bottom Line

ISP proxy = fixed residential proxy

If you see the term "static residential proxy," it's the same thing as an ISP proxy.
