Summary

ViaTec Telecom

Brazil · AI-generated

isp residential brazil cable

VIATEC TELECOMUNICACOES LTDA is the AS handle for ViaTec Telecom.

What it's used for

  • The space carries residential access traffic, evidenced by the reverse DNS record viatectelecom.com.br and the netname 230675 associated with the registrant VIATEC TELECOMUNICAÇÕES LTDA.
  • The AS announces 2048 IPv4 addresses across 1 prefix and 3 IPv6 prefixes, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
  • As a regional cable and DSL ISP, the traffic consists of subscriber eyeballs and residential broadband connections.

Notable

  • The RDAP registrant VIATEC TELECOMUNICAÇÕES LTDA matches the AS holder name, confirming consistent ownership of the address space.
  • The inventory consists of a single contiguous IPv4 block, 201.158.8.0/21, and three IPv6 prefixes, representing a compact and focused address 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.
