AS11419 AS11419 - TELEFONICA BRASIL S.A
Unclassified LACNIC
Summary
Telefônica Brasil S.A. (Vivo)
isp enterprise legacy
AS11419 is held by Telefônica Brasil S.A., the operator behind the Vivo brand and one of the largest carriers in Brazil. It is a secondary AS rather than the company's backbone: 31 IPv4 prefixes (about 36,000 addresses) and IPv6 out of 2804:e00::/32, behind a single observed neighbour.
What it's used for
Corporate and dedicated-access customer space, on the evidence available. The single observed neighbour tells you this is a leaf hanging off Telefônica's own network, not a peering AS. The prefixes sit in the Brazilian ranges Telefônica holds (179.131.0.0/16 space, 200.196.224.0/19, 200.229.192.0/20, 189.8.64.0/19) and are announced in /20 and /21 chunks.
What tips this away from consumer broadband is who the space is delegated to. One /24 inside 200.196.224.0/20 is registered in the Brazilian registry to Sociedade Unificada Paulista de Ensino Renovado Objetivo, the São Paulo education group behind Universidade Paulista, and the one reverse-DNS record recovered on 200.229.200.5 resolves to ticbrasil.com.br, a business domain rather than a subscriber pool. Provider space subdelegated to named corporate and institutional customers is what a carrier's enterprise/dedicated-link AS looks like. There is no dsl, pppoe or dynamic naming anywhere in the sample, which is what a Vivo residential access AS would be dense with.
Notable
Registro.br dates the AS to 1999 with a last change in 2019, and the holder record carries Telefônica Brasil's CNPJ, so the number has stayed inside the same corporate lineage through the Telesp-to-Vivo consolidation.
Most RDAP lookups on the individual prefixes failed. That is missing data, not clearance, and the corporate-customer reading rests on the two records that did resolve, so it is offered with less than full confidence.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
