Summary

Cosmos Business Systems

Greece · AI-generated

business it telecom greece

The AS handle COSMOS-ASN is held by Cosmos Business Systems S.A.

What it's used for

  • The address space carries infrastructure for an IT and telecommunications provider, as indicated by the netname GR-LANCOM-20210212 and registrant LANCOM DBM; Lancom Ltd.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small-scale business or internal corporate estate rather than a large access network
  • Traffic from this AS represents office workers and IT infrastructure endpoints for a Greek company specializing in computer networking products, IT infrastructure, and software consulting

Notable

  • The registrant LANCOM DBM; Lancom Ltd. for the announced prefix differs from the AS holder Cosmos Business Systems S.A., suggesting leased space or a specific service arrangement
  • The address inventory consists of a single /24 block (185.236.140.0/24) with no IPv6 prefixes, indicating a compact, single-site or limited-deployment footprint

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
