AS27843 is operated by On Empresas S.A.C., a Peruvian telecommunications provider also known as Optical Networks.

What it's used for

  • The address space is primarily registered to ON EMPRESAS S.A.C., with netnames such as 161.132.128.0 - 161.132.143.255 and 181.177.224.0 - 181.177.255.255.
  • The AS announces 129024 IPv4 addresses across 189 prefixes and 18 IPv6 prefixes, maintaining 17 observed neighbours, a ratio consistent with a regional network service provider.

Notable

  • Registrants for the majority of the largest prefixes align with the announcer, identified as ON EMPRESAS S.A.C., though some blocks like 38.19.152.0/21 are registered to Cogent Communications, LLC and 161.132.24.0/21 to Red Cientifica Peruana.
  • The operator is identified in secondary sources as Win Empresas S.A.C., a telecommunications enterprise based in Lima, Peru, incorporated in 2013.
  • The inventory includes a mix of /20 and /21 blocks, with a significant portion of the 161.132.0.0/16 range subdivided into multiple smaller prefixes.

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: 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.
