business brazil ipv4

The AS handle ENTERPRISE SERVICES BRASIL SERVICOS DE TECNOLOGIA is held by Enterprise Services Brasil Servicos de Tecnologia.

What it's used for

  • The address space carries a single IPv4 block, 201.33.128.0/20, with the netname 91082 and registrant matching the AS holder.
  • The inventory consists of 4096 IPv4 addresses and 1 IPv6 prefix, with 2 observed neighbours, suggesting a small-scale business or internal corporate network rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix matches the AS holder, confirming consistent ownership.
  • The address inventory is compact, comprising one IPv4 /20 block and one IPv6 /48 prefix, typical of a dedicated corporate or service provider estate.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
