Summary

Viamar Telecom

Brazil · AI-generated

isp residential cable regional

AS61856 is operated by Viamar Telecom.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries pointing to viamartelecom.com.br and netnames registered to the operator.
  • The AS announces 4,096 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 2 observed routing neighbours, indicating a regional access provider rather than a transit carrier.
  • Traffic consists of subscriber eyeballs for cable and DSL services in Brazil, supported by the operator's consumer-facing mobile application and regional ISP classification.

Notable

  • All four IPv4 prefixes list Viamar Telecom as the registrant, matching the AS holder.
  • The inventory consists of four /22 blocks and a single /32 IPv6 prefix, representing a modest, contiguous address estate for a regional ISP.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
