About this network

OSNET is operated by OSNET, a Puerto Rican internet service provider.

What it's used for

• The address space carries residential and business internet services in Puerto Rico, evidenced by netnames such as OSNET-CGNT-NET-1, OSNET, and OSNET-1.
• With 31,488 IPv4 addresses announced across 46 prefixes and 81 observed neighbours, the ratio suggests a regional access network providing connectivity to end-users rather than a major transit provider.

Notable

• Registrants include OSNET, Cogent Communications, LLC, American Registry for Internet Numbers, and TLD of Puerto Rico, indicating a mix of owned and leased address space.
• The address inventory is fragmented into many small prefixes, including /22s and /23s, consistent with a local ISP managing diverse customer segments.
