Summary

ITS Telecomunicações

Brazil · AI-generated

telecom residential brazil nsp

AS28186 is operated by ITS Telecomunicações LTDA.

What it's used for

  • The address space carries static residential and business connections, evidenced by reverse DNS entries such as 255-231-8-177.STATIC.itsweb.com.br and 0-116-136-177.STATIC.itsweb.com.br.
  • The AS announces 69,632 IPv4 addresses across 163 prefixes and 140 IPv6 prefixes, while maintaining 113 observed neighbours; this high address-to-neighbour ratio indicates a regional access network rather than a transit provider.

Notable

  • All sampled RDAP registrants match the AS holder, consistently listing ITS TELECOMUNICACOES LTDA for prefixes including 177.8.224.0/20 and 187.44.152.0/21.
  • The inventory is finely subdivided into numerous /21 and /22 blocks, reflecting a site-by-site segmentation typical of a regional telecommunications provider serving multiple municipalities in Brazil.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
