Detection & anti-detect
How bot detection scores a request, and which signals a proxy can and cannot change. 6 articles.
- Carrier IP Reputation: Why Mobile IPs Score Better Than DatacenterHow IP reputation is actually computed — ASN classification, abuse history, address density, published hosting ranges — and why carrier CGNAT scores well, datacenter scores worst, and shared residential sits in between with borrowed history.
- DNS Leaks on Mobile Proxies — How They Happen, and How We Found OursA proxy can exit from exactly the right place and still leak, because DNS is a separate path from your traffic. The socks5 vs socks5h cause, the CDN routing failure it produces, and the fleet-wide leak we shipped and fixed.
- How Websites Detect Proxies in 2026Detection is a scoring system, not a single lookup. The full stack of signals a modern anti-bot system reads — IP reputation, TLS fingerprint, TCP/IP stack, header order, browser fingerprint, behaviour and account history — and exactly which one a proxy changes.
- JA3 vs JA4 TLS Fingerprinting ExplainedWhat a TLS ClientHello reveals about your client, how JA3 hashed it, why Chrome's randomised extension order broke JA3 and JA4 replaced it, why a Python request is identifiable on sight, and why changing your User-Agent cannot help.
- TCP/IP Fingerprinting: How Your OS Leaks Through Every ConnectionWhat the SYN packet reveals about your operating system — initial TTL, window size, MSS, window scale and TCP option order — how passive p0f-style fingerprinting reads it, what JA4T notation means, and why this layer cannot be fixed from a browser.
- WebRTC Leaks: How They Expose Your Real IP and How to TestWebRTC discovers peers by deliberately enumerating your addresses over UDP, on a path your proxy may never touch. Why turning it off is its own fingerprint, why the replace setting is the right answer, and why SOCKS5 UDP ASSOCIATE matters.
