cable isp residential regional

The AS handle AS28218 is held by Tv Cabo de Presidente Venceslau S/S Ltda. EPP.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as 186-219-74-0.tcvnet.com.br and 189-124-2-0.tcvnet.com.br.
  • The network announces 7424 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio indicative of a regional access provider rather than a transit carrier.

Notable

  • All registrants for the announced prefixes are consistent with the AS holder, specifically Tv Cabo de Presidente Venceslau S/S Ltda. EPP.
  • The address inventory is subdivided into two main blocks, 186.219.64.0/22 and 189.124.0.0/21, with netnames 160120 and 406394 through 406396 respectively.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
