Summary
Telemar Norte Leste (Oi / V.tal)
isp broadband eyeball backbone
Telemar Norte Leste S.A. is the legacy fixed-line network of the Oi group (formerly Telemar and Brasil Telecom) in Brazil. Its infrastructure is now operated by V.tal, a neutral wholesale fibre network.
What it's used for
- Fixed broadband and telephony across much of Brazil, plus wholesale fibre transport carried through V.tal.
Notable
- An "eyeball" network on the retail side — addresses front consumer home broadband connections — while increasingly acting as wholesale backbone under V.tal.
- Oi's financial restructuring led to its fibre assets being spun into V.tal, which now runs this network as neutral infrastructure for many ISPs.
Interesting
- V.tal was created as one of Latin America's largest neutral fibre networks, built on the backbone that Oi/Telemar had deployed nationwide.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
