Proxy Glossary

Key terms and definitions in the proxy, anti-detect, and web scraping industry.

Proxy Server

An intermediary server that routes your internet requests through its own IP address, hiding your real IP from the target server.

Residential Proxy

A proxy that uses an IP address assigned by an ISP to a real home user. Highly authentic and difficult to detect as a proxy.

Datacenter Proxy

A proxy hosted in a cloud data center. Fast and affordable, but more easily detected by anti-bot systems due to known datacenter IP ranges.

Mobile Proxy

A proxy that routes traffic through real mobile devices on 3G/4G/5G networks. Carries the highest trust score among proxy types.

Rotating Proxy

A proxy setup where the IP address changes automatically on each request or at set intervals, reducing the risk of detection and blocking.

Sticky Session

A proxy configuration that keeps the same IP address for a defined period, useful for maintaining sessions on websites that track IP consistency.

SOCKS5 Proxy

A versatile proxy protocol that supports TCP and UDP traffic. More flexible than HTTP proxies and works with a wider range of applications.

HTTP Proxy

A proxy that handles HTTP/HTTPS web traffic. The most common type for web scraping and browsing.

Anti-Detect Browser

A browser that allows you to create isolated profiles with unique fingerprints, preventing websites from linking multiple sessions to the same identity.

Browser Fingerprint

A unique set of browser characteristics (user agent, screen size, fonts, canvas, WebGL, etc.) that websites use to identify and track users.

IP Ban

When a website blocks access from a specific IP address, typically triggered by suspicious activity, rate limit violations, or policy violations.

Rate Limiting

A server-side mechanism that restricts the number of requests from a single IP within a time window, used to prevent scraping and abuse.

robots.txt

A standard file that websites use to communicate crawling rules to bots. Ethical scrapers should always check and respect robots.txt directives.

CAPTCHA

A challenge-response test used to distinguish humans from bots. Common CAPTCHAs include reCAPTCHA v2/v3, hCaptcha, and image-based puzzles.

Web Scraping

The automated extraction of data from websites, typically by parsing HTML or interacting with web pages programmatically.

Headless Browser

A web browser that runs without a graphical interface. Used in automation and scraping to render JavaScript-heavy pages.

IP Pool

A collection of IP addresses managed by a proxy provider, used to rotate requests and distribute traffic to avoid detection.

Geo-targeting

The ability to route requests through proxies in specific countries or cities to access geo-restricted content or verify localized ads.
