About this network

AS11802 belongs to CIASC, the Centro de Informática e Automação do Estado de Santa Catarina — the state-owned IT company of Santa Catarina, Brazil, based in Florianópolis. Founded in 1975 as PRODASC and converted to a wholly public company in 2005, it is the body that runs information-technology and e-government services for the state administration.

What it's used for

Public-sector service delivery, not commercial connectivity. RIS observes 4 IPv4 prefixes totalling 12,288 addresses, 2 IPv6 prefixes, and 4 observed neighbours — a modest, multi-homed footprint sized for hosting applications rather than carrying transit. All four IPv4 blocks are registered through LACNIC to CIASC itself, so registrant and announcer are the same entity with nothing third-party in between.

What the space carries is government systems for Santa Catarina at every level CIASC serves — state executive agencies, and by extension the municipal and judicial bodies that contract it for data processing and hosting. The one reverse-DNS record sampled points at a sc.gov.br municipal-government host, which is consistent with a state IT company that also runs services on behalf of city administrations rather than only its own.

Notable

Brazilian states routinely run these empresas de processamento de dados — CIASC in Santa Catarina, and equivalents in most other states — as public companies with their own ASNs and data centres. In 2026 CIASC was formally recognised as a Scientific, Technological and Innovation Institution, which broadens its remit beyond straightforward government IT operations.
