Summary

PortalSAT Telecom

Brazil · AI-generated

isp cable dsl regional

AS53156 is operated by PortalSAT Telecom.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries like 0.4.211.186.portalsat.net.br and the netname 144798.
  • The AS announces 4096 IPv4 addresses in a single /20 prefix and 1 IPv6 prefix, with 4 observed neighbours, indicating a regional access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for cable and DSL services in the Bahia region of Brazil.

Notable

  • The RDAP registrant PortalSAT Telecom matches the AS handle and the reverse DNS domain portalsat.net.br.
  • The address inventory is a single contiguous /20 block, typical of a regional ISP managing its own allocated space.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
