Classification by IP Origin
The most important proxy classification:
Residential Proxies — IPs from consumer home broadband connections. High trust, moderate speed.
Datacenter Proxies — IPs from cloud/hosting provider servers. Fast, cheap, detectable.
ISP Proxies (Static Residential) — Residential-registered IPs on server hardware. Best balance.
Mobile Proxies — 4G/5G carrier IPs from real SIM devices. Highest trust, most expensive.
Peer-to-Peer Proxies — A subtype of residential using volunteer device networks.
Classification by Rotation Method
Static Proxies — Fixed IP, same address every request. Used for account management.
Rotating Proxies — New IP per request or interval. Used for scraping and data collection.
Backconnect Proxies — Gateway that routes to rotating IPs automatically. Same as rotating.
Sticky Session Proxies — Rotating pool with configurable session duration. Hybrid approach.
Classification by Protocol
HTTP Proxies — Handle only HTTP traffic. Application layer.
HTTPS Proxies — Tunnel encrypted HTTPS connections. Standard for web use.
SOCKS4 Proxies — TCP socket tunneling, no authentication, no UDP.
SOCKS5 Proxies — TCP + UDP socket tunneling, username/password auth, DNS leak protection.
Socks5 is the most flexible; HTTP/HTTPS is simplest for web work.
Classification by Sharing Level
Private (Dedicated) Proxies — Exclusive use by one customer. Clean reputation.
Shared Proxies — Used by multiple customers simultaneously. Cheaper, contamination risk.
Semi-dedicated Proxies — Shared between 2–5 customers. Middle ground.
Classification by Anonymity Level
Transparent Proxies — Server knows you're using a proxy and your real IP. Used for caching.
Anonymous Proxies — Server knows you're using a proxy but not your real IP.
Elite (High-Anonymity) Proxies — Server cannot tell you're using a proxy. No proxy headers sent.
For web scraping: always use elite/high-anonymity proxies. Residential and ISP proxies are inherently elite because they appear as normal user traffic.
Specialized Proxy Types
Virgin Proxies — IPs with no prior usage history. Premium for platforms with strict new-IP detection.
IPv6 Proxies — Use IPv6 addresses. Very cheap, limited target compatibility.
Dedicated Mobile Ports — Exclusive SIM connection maintained for one customer.
Backconnect Rotating — The standard rotating residential proxy pool model.
SERP Proxies — Residential proxies pre-validated for Google SERP scraping.
Sneaker Proxies — ISP/residential proxies pre-tested against major sneaker retailers.
