About this network

AS28202 is operated by Master Internet, a Brazilian cable television and internet service provider.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries such as mastercabo.com.br and soumaster.com.br with hostnames indicating cable (cb) and fiber (fb) connections.
• The AS announces 212,992 IPv4 addresses across 133 prefixes and 45 IPv6 prefixes, while maintaining 69 observed neighbours; this high address-to-neighbour ratio is characteristic of an access network serving end-users rather than a transit provider.

Notable

• All sampled RDAP registrants are listed as MASTER S/A, which aligns directly with the AS holder name.
• The address inventory is finely subdivided into numerous /19, /20, and /21 blocks, reflecting a large, segmented customer base typical of a regional cable operator.
