Brazil · AI-generated

business telecom legacy

AS23002 is operated by Telmex do Brasil Ltda., a Brazilian telecommunications entity.

What it's used for

  • The address space carries corporate and service infrastructure, evidenced by the reverse DNS record dns2.hannover.com.br and registrant netnames 49797 and 23918.
  • The AS announces 8192 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale access or internal corporate network rather than a transit provider.

Notable

  • Telmex do Brasil Ltda. is a subsidiary of Telmex Internacional, S.A.B. de C.V., providing value-added services such as network integration and outsourcing in Brazil.

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 1,779 prefixes, as published 2026-10-23. 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.
