Proxy Mechanics
How Proxies Work
Proxies are a flexible gateway for your device's connection to every website. Without a proxy, websites send content back to your device's unique IP (Internet Protocol) address. With a proxy, websites only send content back to the proxy's IP address, which then forwards web content to your device:
When you make a web request through a proxy:
- Your Device (IP: 12.34.56.78 - Ontario, CA) initiates a request for a website.
- The Proxy Server (IP: 98.75.54.32 - Chicago, IL) receives and forwards the request to the web server.
- The Web Server (Host: google.com - Chicago, IL) just returns the web content to the proxy server.
- The Proxy Server securely forwards the web content back to your device.
What Websites Can Detect
Without a proxy, websites you access can see your unique IP address (and the associated geolocation information), any data shared by your browser, and most critically – any data that can be linked to your IP and browsing "fingerprint" through various commercial & government databases that aggregate personal data!

Detectable IP Information
Your IP address is your device's unique identifier assigned by our Internet Service Provider (ISP) for connecting to the Internet. For your request to this website (squidproxies.com), our web server sees:
...
From there, popular IP address geolocation databases typically share the information associated with your IP address, including the ISP and approximate location:
| IP | ... |
| City | ... |
| Region | ... |
| Postal Code | ... |
| Country | ... |
| Continent | ... |
| Timezone | ... |
| ISP Organization | ... |

These popular geolocation services maintain independent IP location databases, so you can test your IP address against additional IP geolocation databases below:
Detectable Browser Fingerprint
Your browser also reveals a tremendous amount of information about your system to websites for applications to optimize your browsing experience. However, sophisticated data aggregators have combined each of these data points together into a "IP + browser fingerprint" which can often be used to uniquely identify your browser and device across all the websites you interact with.
For example, here is some of the information shared by your current browser:
| Your Fingerprint ID | ... |
| Browser User Agent | ... |
| Browser Version | ... |
| Operating System | ... |
| CPU Information | ... |
| Screen Resolution | ... |
| Screen Colors | ... |
| Device Locale | ... |
| Device Timezone | ... |
| System Fonts | ... |

Linkable Personal Data
Various organizations also maintain extensive databases to link IP addresses to households -– including linking IP addresses and browser fingerprints to names, addresses, phone numbers, and social media profiles – for marketing, legal, and law enforcement purposes.
Some examples of such databases include:
| Database | Description |
| El Toro's Household DB | El Toro's patented algorithm provides marketers with accurate, traceable and transparent targeting that matches IP addresses to precise household addresses… with up to a "95% confidence level". |
| Palantir's Gotham DB | Palantir's Gotham database aggregates billions of records, including IP addresses from ISP subscriber records to individuals, addresses, phone numbers, and social security numbers, for law enforcement and intelligence purposes. |
| Oracle's BlueKai | Oracle's BlueKai platform collects and aggregates user data, including IP addresses, to build detailed consumer profiles for targeted advertising. This data encompasses browsing behavior, purchase history, and demographic information. |
| Tapad's Device Graph | Tapad (owned by Experian) links IP addresses and device identifiers to identify and target consumers across multiple devices within a household. This facilitates consistent messaging and measurement across platforms. |
| NSA's XKeyscore | The NSA's XKeyscore program collects and analyzes global internet data, including IP addresses, to identify and monitor individuals' online activities for intelligence purposes. It allows analysts to search and retrieve vast amounts of digital communications. |
| GCHQ's Karma Police | The UK's GCHQ operated the Karma Police program to collect IP addresses and web browsing histories, aiming to build profiles of internet users for surveillance and intelligence gathering. |
| Russia's SORM | Russia's System for Operative Investigative Activities (SORM) mandates ISPs to provide the Federal Security Service (FSB) with access to users' communications, including IP addresses, for surveillance and monitoring purposes. |

Common Mistakes to Avoid
Learn from common pitfalls to ensure successful proxy implementation:
Choosing Based on Price Alone
The cheapest option often leads to poor performance and wasted time. Consider total cost of ownership including success rates.
Ignoring Geographic Requirements
Not matching proxy locations to your target audience can lead to blocked requests, irrelevant data, or reduced performance.
Over-aggressive Request Patterns
Sending too many requests too quickly can trigger rate limits and IP bans, defeating the purpose of using proxies.
Neglecting Security Practices
Using unsecured proxy connections or sharing credentials can expose sensitive data and compromise operations.
Not Monitoring Performance
Failing to track success rates and response times means missing optimization opportunities and potential issues.
Inadequate Testing
Skipping proper testing phases can lead to production failures and wasted resources on the wrong proxy type.

How to Evaluate Proxy Providers
When choosing a proxy provider, consider these critical factors to ensure you select the right service for your specific needs and requirements:
Trust & Reputation
The number one factor between you and your proxy provider. Look for established companies with transparent practices and positive reviews from legitimate customers.
Acceptable Use Policies
Make sure the provider's allowed use cases align with your intended purposes. Some providers restrict certain activities like social media management or scraping specific websites.
Security Practices
Evaluate how the provider handles your data and connection security. Look for providers with secure authentication methods and encryption for sensitive data.
Logging Policies
Understand what information the provider logs about your activity. Privacy-focused providers should maintain minimal logs and have clear retention policies.
Proxy Source
Determine if the provider owns their infrastructure or resells another company's proxies. Direct providers typically offer better support and more consistent service.
Proxy Performance
Test for speed and reliability before committing to a provider. Look for services offering trial periods or money-back guarantees to assess performance.
Proxy Reliability
Check uptime guarantees and real-world performance. A provider should maintain at least 99.9% uptime for their proxy services.
IP Quality
Verify that the provider's IPs can access the websites and services you need. Clean IPs with good reputations are essential for successful operations.
IP Pool Size
Ensure the provider has a sufficiently large and diverse pool of IPs. A larger pool reduces the risk of IP bans and improves rotation capabilities.
