Summary

Departamento de Agua e Esgoto de Bauru

Brazil · AI-generated

government municipal water utility

AS52621 is held by Departamento de Agua e Esgoto de Bauru.

What it's used for

  • The space carries infrastructure for a municipal water and sewage utility, as indicated by the registrant name and netname 200637.
  • The AS announces 256 IPv4 addresses in a single /24 prefix and one IPv6 /48 prefix, with only one observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative and operational systems for the city of Bauru's water and sewage department.

Notable

  • The RDAP registrant matches the AS holder exactly, with the netname 200637 assigned to the same entity.
  • The address inventory is minimal, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a small municipal government entity.

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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
