isp residential brazil cable

AS61810 is operated by Webfibra Telecomunicações Eireli ME.

What it's used for

  • The space carries residential broadband access, evidenced by the registrant netname 231911 and the operator's classification as a Cable/DSL/ISP.
  • The AS announces 1024 IPv4 addresses within a single /22 prefix (201.158.56.0/22) and one IPv6 prefix (2804:19a8::/32).
  • With only one observed neighbour, the network functions as a local access provider rather than a transit hub, serving end-user traffic for its regional subscriber base.

Notable

  • The RDAP registrant Webfibra Telecomunicações Eireli ME matches the AS holder name exactly.
  • The address inventory consists of a single contiguous IPv4 block and one IPv6 prefix, indicating a compact, self-contained deployment.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-08, 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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
