isp residential cable dsl

AS61924 is operated by 3E Telecom, a regional cable and DSL provider in Brazil.

What it's used for

  • The address space carries residential dynamic subscribers, as indicated by reverse DNS entries such as 255-91-130-201.dynamic.3enet.com.br and 254-93-130-201.dynamic.3enet.com.br.
  • The network announces 2048 IPv4 addresses within a single /21 prefix (201.130.88.0/21) and one IPv6 prefix (2804:180c::/32), while maintaining 18 observed routing neighbours.
  • Traffic consists of subscriber eyeballs for cable and DSL customers in the region, consistent with the operator's classification as a regional ISP.

Notable

  • The RDAP registrant 3E TELECOM matches the AS handle and the reverse DNS domain 3enet.com.br, confirming consistent ownership.
  • The inventory is compact, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a regional access provider rather than a transit carrier.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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 1,768 prefixes, as published 2026-10-12. 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.
