Brazil · AI-generated

residential isp brazil cgnat

AS61937 is operated by Oquei Telecom Ltda.

What it's used for

  • The address space carries residential customer traffic, evidenced by reverse DNS entries such as 189.45.167.255.cgnat.customer.oquei.com.br and 200-95-219-254.customer.oquei.com.br.
  • The network announces 14,592 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, with only 2 observed routing neighbours, indicating an access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for a regional Brazilian telecommunications provider, utilizing CGNAT for IPv4 address conservation.

Notable

  • All registrants for the announced prefixes are listed as Oquei Telecom Ltda, matching the AS holder.
  • The address inventory is fragmented across multiple /20, /21, /22, /23, and /24 blocks, including ranges in the 189.45, 200.95, 45.70, 45.229, and 168.195 spaces.

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: 454 networks and 1,854 prefixes, as published 2026-11-09. 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.
