Understanding Proxy Types

Choosing the right proxy type is the most critical decision for any proxy-dependent operation. Each type offers different performance, cost, and detection characteristics optimized for specific use cases.

Datacenter Proxies

Fastest

IPs from cloud providers and data centers (AWS, Google Cloud, DigitalOcean, Hetzner). Not associated with ISPs or physical locations - purely virtual infrastructure.

Speed: 1-10ms latency
Price: $2-10/month
Trust: 30-50%
Detection: High (60-80%)
Best for: Basic web scraping, API testing, low-security tasks
Avoid for: Social media, e-commerce accounts, Google/Facebook scraping

Residential Proxies

Balanced

IPs from real residential internet connections (Comcast, Spectrum, BT, etc.). Legitimate home user IPs that websites trust as genuine traffic.

Speed: 20-100ms
Price: $5-15/GB
Trust: 85-95%
Detection: Low (10-20%)
Best for: Web scraping, price monitoring, SERP tracking, account management
Sweet spot: Best balance of cost, performance, and trust for most use cases

Mobile Proxies (4G/5G LTE)

Premium

IPs from real mobile carriers (Verizon, AT&T, Vodafone, T-Mobile). Genuine smartphone/tablet IPs that platforms heavily favor since most users access via mobile.

Speed: 30-150ms
Price: $89-150/mo
Trust: 95%+
Detection: Very Low (2-5%)
Best for: Social media, e-commerce accounts, sneaker bots, high-security platforms
Highest success rate: 95%+ for bypassing Instagram, Facebook, Amazon detection

Proxy Protocols: HTTP vs SOCKS5

Understanding proxy protocols is essential for choosing the right solution for your application. HTTP and SOCKS5 operate at different network layers with distinct capabilities and use cases.

HTTP/HTTPS Proxies

Application-layer proxies that work exclusively with web traffic (HTTP and HTTPS protocols).

Understand HTTP headers (can modify User-Agent, Referer, etc.)
Faster for web requests (optimized for HTTP protocol)
Support authentication (username/password)
Limited to web traffic only - cannot proxy FTP, SMTP, etc.

SOCKS5 Proxies

Transport-layer proxies that work with ANY internet protocol, not just HTTP/HTTPS.

Protocol-agnostic (HTTP, HTTPS, FTP, SMTP, P2P, WebSockets)
Work with any application (browsers, games, VoIP, torrents)
Support UDP traffic (required for VoIP, gaming, video streaming)
Lower latency for non-HTTP protocols

Choosing the Right Protocol

Use HTTP proxies for: Web scraping, API calls, browser-based automation, simple HTTP/HTTPS traffic

Use SOCKS5 proxies for: Automation tools (Jarvee, Socinator, Scrapy), gaming, VoIP/calling apps, torrenting, any multi-protocol application, maximum compatibility

When in doubt: Choose SOCKS5 - it works for everything HTTP does plus more

IP Rotation Strategies

IP rotation is critical for scaling proxy operations and avoiding detection. Understanding when and how to rotate IPs determines success or failure for most proxy use cases.

Rotating Proxies (Dynamic IPs)

IP address changes automatically at defined intervals or per request. Ideal for high-volume operations where you need to distribute requests across many IPs to avoid rate limits.

Best for: Web scraping (thousands of pages), price monitoring, SERP tracking, data collection, competitor research

Sticky/Static Proxies (Persistent IPs)

Same IP address maintained for extended period (hours, days, or weeks). Essential for scenarios requiring IP consistency and account trust.

Best for: Social media accounts, e-commerce seller accounts, online banking, any account management where platforms track login IP consistency

Frequently Asked Questions

What are the main types of proxies and how do they differ?

Datacenter proxies ($2-10/month) are fastest but easily detected. Residential proxies ($5-15/GB) offer balanced performance and trust. Mobile proxies ($89-150/month) have highest trust scores (95%+) for social media and e-commerce. Choose based on target platform security and budget.

What is the difference between HTTP and SOCKS5 proxies?

HTTP proxies work only with web traffic (HTTP/HTTPS), while SOCKS5 supports ALL protocols (HTTP, FTP, SMTP, VoIP, gaming). Use HTTP for simple web scraping, SOCKS5 for automation tools, gaming, VoIP, or maximum compatibility.

How does IP rotation work and when should I use it?

IP rotation changes your proxy IP automatically per request or time interval. Use rotating proxies for high-volume scraping and data collection. Use sticky/static proxies for account management where platforms track login IP consistency (social media, e-commerce).
