Bahia · network infrastructure

Salvador holds most of the capacity the snapshot records. BR.Digital Salvador (SDR1) lists 9 networks, IDC Webfoco 4, and Softdados IDC and Softdados IDC at Telxius CLS 3 each, with several smaller Salvador sites carrying one network apiece. Away from the capital, IDC Infortel in Eunapolis and Viva Tecnologia Telecom in Camaçari list 3 each, and BR.Digital Feira de Santana (FSA1) lists 2. Traffic can meet inside the state: IX.br (PTT.br) Feira de Santana counts 27 participants, so networks in Bahia have somewhere in-state to exchange traffic instead of carrying all of it out.

An address block is placed in Bahia because the operator registered it to an address there, not because a device sits in Salvador or Feira de Santana. Mobile networks loosen that further. Claro (AS22085), TIM (AS26615) and Vivo (AS26599, AS27699) gather subscribers behind regional gateways, so a handset connected in Bahia can present an address that a lookup puts in another state, and a block labelled Bahia can be answered by equipment somewhere else in the country.

Reading the prefix beats trusting a city label. Check the origin ASN on the specific address and the netname on the registration; a block announced by AS26615 is on TIM's mobile network whatever city a database shows. Facility records help for fixed hosting, where 36 network presences across the 19 recorded sites give a short list of candidates, but they say nothing about where a mobile subscriber stands at any given moment.
