Overview

Modern headless Chromium scrapers hosted on Tencent Cloud (AS132203), Alibaba Cloud (AS45102), and Huawei Cloud (AS136907) rotate outbound IPv4 addresses across /10 and /16 CIDR blocks (43.128.0.0/10, 47.74.0.0/16, 101.32.0.0/15) on every HTTP request, spoof legacy mobile User-Agents (CPU iPhone OS 13_2_3), hammer Next.js ? _rsc= payloads, and pollute Google Analytics 4 with synthetic sessions.

utilvo-edge-shield provides programmatic request inspection, CIDR/ASN matching, and WAF rule generation while strictly whitelisting verified search engine crawlers (Googlebot, Bingbot, Applebot, DuckDuckBot, YandexBot).
