About this network

AS22689 is operated by Sercomtel S/A Telecomunicacoes.

What it's used for

• The address space carries residential access infrastructure, evidenced by reverse DNS entries such as r719-pf-xingu.ibys.com.br and r224-pw-xambre.ibys.com.br, which indicate CPE and access node naming conventions.
• The network announces 160,000 IPv4 addresses across 39 prefixes and 31 IPv6 prefixes, while maintaining 41 observed neighbours; this high address-to-neighbour ratio is characteristic of an access or eyeball network rather than a transit provider.

• The address inventory consists of multiple /18 and /19 blocks, with finer subdivisions into /20, /21, and /22 prefixes, reflecting a segmented allocation typical of a regional telecommunications provider.
