Summary

Brazil · AI-generated

residential isp brazil access

AS22689 is operated by Sercomtel S/A Telecomunicacoes.

What it's used for

  • The address space carries residential access infrastructure, evidenced by reverse DNS entries such as r719-pf-xingu.ibys.com.br and r224-pw-xambre.ibys.com.br, which indicate CPE and access node naming conventions.
  • The network announces 160,000 IPv4 addresses across 39 prefixes and 31 IPv6 prefixes, while maintaining 41 observed neighbours; this high address-to-neighbour ratio is characteristic of an access or eyeball network rather than a transit provider.

Notable

  • All sampled registrants for the largest prefixes, including 186.236.128.0/18 and 187.0.64.0/18, are listed as SERCOMTEL S/A TELECOMUNICACOES, matching the AS holder.
  • The address inventory consists of multiple /18 and /19 blocks, with finer subdivisions into /20, /21, and /22 prefixes, reflecting a segmented allocation typical of a regional telecommunications provider.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
