About this network

CASTLES-AS is operated by Castles LLC.

What it's used for

• The address space carries hosting and DDoS protection services, evidenced by netnames like RS-CASTLES and reverse DNS entries such as partner-protected-127.211.42.5.hostingrust.ru and mc.hypemc.pro.
• The AS announces 4608 IPv4 addresses across 17 prefixes and 2 IPv6 prefixes, while maintaining 25 observed neighbours; this ratio indicates a hosting or service provider role rather than a large-scale transit or access network.
• Traffic from this AS consists of web and API endpoints, game servers, and protected infrastructure for clients seeking DDoS mitigation, consistent with the operator's business model.

Notable

• Registrants for the majority of prefixes align with the announcer, listing Castles.pro; Castles LLC, though some blocks are registered to Wireless Ltd, QWARTA LLC, and NetCrafters.
• The address inventory is fragmented, with most prefixes being /24s and one /23, suggesting a collection of smaller leased or acquired blocks rather than a single contiguous allocation.
