Understanding Different Types of Proxies

With so many proxy networks on the market, choosing the correct IP type is critical for the success of your scraping, marketing, or automation campaigns. Use the wrong type, and you might get blocked instantly. Use an over-qualified proxy type, and you’ll waste thousands of dollars.

If you are entirely new to this topic, we recommend starting with our beginner guide on What is a Proxy.

1. Datacenter Proxies

Datacenter proxies are the most common and accessible type of IP address. Instead of being provided by an Internet Service Provider (ISP), these IPs come from secondary corporations like AWS, Google Cloud, DigitalOcean, and other major data centers.

Because they are tied to massive cloud infrastructure, they are incredibly fast and inexpensive. However, because their ASNs (Autonomous System Numbers) clearly identify them as belonging to server farms rather than real human homes, high-security websites like Amazon or Google can easily detect and block them using basic anti-bot algorithms.

Best for: Non-protected targets, massive scale volume tasks, basic web scraping, and server-to-server API testing. Test your datacenter IPs using our Proxy Checker.

2. Residential Proxies

Residential proxies use real IP addresses provided by an Internet Service Provider (like AT&T or Comcast) to ordinary homeowners. These IPs belong to real desktop and laptop devices connected to residential networks.

When you route your traffic through a residential proxy, your requests appear indistinguishable from an everyday user sitting in their living room. As a result, residential IPs enjoy an exceptionally high "trust score," making it highly unlikely that target websites will block or captcha your traffic.

Best for: Social media scraping, SEO monitoring, sneaker botting, ad verification, and scraping sophisticated targets equipped with robust anti-bot protections (Cloudflare, Datadome). Find top providers in our Best Proxies 2026 Guide.

3. Mobile Proxies (4G & 5G)

The pinnacle of IP trust scores. Mobile proxies are IPs temporarily leased to mobile devices (smartphones, tablets) by cellular network carriers (like T-Mobile, Vodafone).

Due to Carrier-Grade NAT (CGNAT), cellular providers share a single IPv4 address among hundreds or thousands of real mobile users simultaneously. Because of this, target websites are terrified to block mobile IPs—doing so might accidentally ban hundreds of legitimate, organic mobile users along with your scraper. This makes mobile proxies practically unblockable.

Best for: High-risk platforms with zero-tolerance bot detection policies like Instagram, LinkedIn, and TikTok.

4. Static ISP Proxies

Static ISP proxies offer the best of both worlds. They are hosted in data centers (giving them exceptional speed and 99.9% uptime uptime), but their IP blocks are officially registered under consumer ISPs.

Because the IP address never changes (unlike rotating residential pools where devices go offline), you can maintain persistent, long-term sessions while still retaining the high trust profile of a residential user.

Best for: Managing multiple long-term accounts (e-commerce storefronts, social media marketing profiles) where a consistent, highly-trusted IP address is mandatory to prevent account suspension.

Protocols: HTTP vs SOCKS5

Beyond the source of the proxy, you also configure the protocol:

• HTTP/HTTPS: Designed specifically for reading web pages. Ideal for standard scraping scripts utilizing tools like Puppeteer, Playwright, or basic cURL requests.
• SOCKS5: A lower-level protocol that can route virtually any type of traffic (TCP or UDP). It is significantly faster and more versatile, making it the choice for gaming, video streaming, torrenting, or advanced application routing.
