Summary

Imicro Provedores de Internet

Brazil · AI-generated

residential isp brazil small

AS28342 is operated by Imicro Provedores de Internet Ltda.

What it's used for

  • The space carries residential internet access, indicated by the registrant name "Provedores de Internet" (Internet Providers) and the single netname 202172.
  • The AS announces 2048 IPv4 addresses within a single /21 prefix (177.130.240.0/21) and has 1 observed neighbour, a ratio consistent with a small access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant IMICRO PROVEDORES DE INTERNET LTDA matches the AS handle and the announced prefix owner.
  • The address inventory consists of a single contiguous /21 block, typical of a small regional ISP managing its own customer base.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,852 prefixes, as published 2026-11-08. 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.
