isp residential brazil access

AS61870 is operated by Gcu Serviços de Provedor Ltda.

What it's used for

  • The address space carries residential and small business internet access in southern Brazil, specifically serving the cities of Guaraniaçu and Nova Laranjeiras.
  • The network announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 3 observed routing neighbours. This low neighbour count relative to the address block size indicates a local access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs connecting to the internet via the operator's local infrastructure.

Notable

  • Both announced IPv4 prefixes (131.0.80.0/22 and 170.246.248.0/22) list Gcu Serviços de Provedor Ltda as the registrant, matching the AS holder.
  • The inventory consists of two /22 blocks and a single /32 IPv6 prefix, representing a modest footprint typical of a regional ISP.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
