LLC "Hostmaster" is best read as a registry and DNS-infrastructure operator, not as a commodity cloud vendor. Its public pages describe the administration of Ukraine's .UA domain, the services around WHOIS, RDAP, DNSSEC and IDN support, the registrar-facing policy surface and recent resilience messaging for the Ukrainian domain infrastructure. That makes Hostmaster relevant to cloud-service dependency coverage because many internet services depend on the domain registry layer before they ever depend on a server, an application stack or a data centre contract.
