About this network

AS28604 is operated by Globo Comunicação e Participações, a major Brazilian media conglomerate.

What it's used for

• The address space carries internal corporate infrastructure, evidenced by reverse DNS records pointing to prt.globo.com (e.g., 186-192-84-0.prt.globo.com).
• The AS announces 16,128 IPv4 addresses across 14 prefixes and 33 IPv6 prefixes, while maintaining 51 observed neighbours. This ratio of moderate address space against a significant number of peering partners suggests a large-scale enterprise network with substantial internal segmentation rather than a typical access provider.

Notable

• All registrants for the largest prefixes are listed as Globo Comunicação e Participaçoes SA, fully aligning with the AS holder.
• The address inventory is finely subdivided into multiple /22 and /23 blocks, consistent with site-by-site segmentation for a large corporate estate.
• The network has been observed in routing tables since 2005-07-19.
