Abuse-Tolerant HostingCTG Server Limited (AS152194, Hong Kong)
CTG Server Limited (AS152194) operates VPS infrastructure spanning Hong Kong, Australia, and US address blocks. All observed IPs return NXDOMAIN on PTR lookup, consistent with disposable attack allocations. The multi-continent footprint — with observed /24s in Australia (118.107.44.0/24), United States (137.220.224.0/24), and Hong Kong (103.230.240.0/24) — indicates a provider that deliberately spreads infrastructure across jurisdictions to complicate abuse response and country-based filtering.
