About this network

AS28577 is operated by Azevedo e Floriani Telecomunicações Ltda., known commercially as Yukanet.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to yukanet.com.br (e.g., 0.218.208.186.yukanet.com.br).
• The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 26 observed neighbours; this ratio of moderate address space against a significant number of peering partners suggests a regional access provider with transit relationships.

Notable

• Registrants for both announced IPv4 prefixes (186.208.216.0/21 and 138.99.52.0/22) match the AS holder, Azevedo e Floriani Telecomunicações Ltda.
• The operator is identified in peering databases as Yukanet, confirming the commercial brand associated with the legal entity.
• The inventory consists of two distinct IPv4 blocks and a single /32 IPv6 prefix, indicating a focused regional footprint rather than a large national or international carrier.
