isp residential cable regional

AS53172 is operated by Next Telecomunicações do Brasil LTDA.

What it's used for

  • The address space carries residential and business broadband traffic, evidenced by reverse DNS records pointing to nexttelecom.net.br (e.g., 186-225-68-0.nexttelecom.net.br).
  • The AS announces 5,120 IPv4 addresses across 2 prefixes and 17 IPv6 prefixes, with only 3 observed neighbours, indicating a regional access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for cable and DSL services in the Brazilian market.

Notable

  • Registrants for both announced prefixes (186.225.64.0/20 and 143.137.8.0/22) match the AS holder, Next Telecomunicações do Brasil LTDA.
  • The inventory is compact, consisting of a single /20 and a single /22 in IPv4, alongside a subdivided IPv6 allocation under 2804:2980::/33.

Reputation

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
