Summary

Telefônica Brasil S.A. (Vivo)

Brazil · AI-generated

isp legacy

AS11706 is held by Telefônica Brasil S.A., the Brazilian incumbent that trades as Vivo (the former Telesp fixed-line business, now Brazil's largest fixed and mobile operator). This is one of several ASNs the group uses, not its main backbone AS.

What it's used for

  • Carrying a slice of Telefônica Brasil's access space. RIS sees 24 IPv4 prefixes / 71,424 addresses and 9 IPv6 prefixes, against only 3 observed neighbours. The low peer count matters: a carrier's transit-selling AS peers with hundreds of networks, so an AS this size with three neighbours is a downstream piece of the group's estate, hanging off Telefônica's own backbone rather than facing the internet on its own.
  • The IPv4 space is one 200.177.0.0/16 aggregate plus a long run of 200.176.x.0/24 deaggregates — legacy Telesp-era space, all in LACNIC.

Notable

  • RDAP resolved for only two of the sampled prefixes, and both came back to org TELEFÔNICA BRASIL S.A (LACNIC handle 4614), confirming the holder against the registry. The rest of the lookups failed; a failed lookup is missing data, not a clearance and not a contradiction, so nothing here rests on them.
  • No PTRs were returned on the 20 addresses sampled. That is a sample, not a finding, and it is why this card does not claim a specific access technology. Without rDNS naming DSL, fibre, or mobile gateways, the exact role of the block inside a group that runs all three cannot be pinned down from routing evidence alone.

Interesting

  • The nine IPv6 prefixes are /40s carved from a single 2804:8480::/32-scale allocation and announced separately, which is a common way large incumbents regionalise IPv6 deployment across states.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
