Summary

Banco de Brasília

Brazil · AI-generated

banking corporate brazil

AS28248 is operated by Banco de Brasília S/A (BRB).

What it's used for

  • The address space is registered under netnames 199608, 199609, and 199610, all attributed to BRB - Banco de Brasília S/A, indicating a dedicated corporate network for the bank.
  • The AS announces 1792 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours. This low neighbour count relative to the address inventory suggests an internal corporate estate rather than a transit or access provider.

Notable

  • All registrants in the RDAP data match the announcer, consistently listing BRB - Banco de Brasília S/A.
  • The address inventory consists of five contiguous IPv4 blocks within the 200.11.0.0/16 range and a single IPv6 /48, reflecting a finely subdivided internal network structure typical of large financial institutions.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
