• The network announces 7,168 IPv4 addresses across 27 prefixes and 1 IPv6 prefix, with only 4 observed neighbours, indicating a hosting or business network rather than a transit provider.
• Traffic from this AS consists of web servers, API endpoints, and hosted applications for business clients, consistent with the operator's role as an internet and communication services company.
