Summary

Arcos Informationssysteme

Germany · AI-generated

business it-services germany

ARCOS-AS is operated by Arcos Informationssysteme GmbH.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by the netname arcos and reverse DNS entries such as pop-vl1-net.arcos.de and pop-vl8-brc.arcos.de.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 2 observed routing neighbours, indicating a small, self-contained business network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate communications and IT services for the company's operations in Baden-Württemberg.

Notable

  • The RDAP registrant Arcos Hostmaster; arcos informationssysteme GmbH matches the AS holder, confirming consistent ownership of the address space.
  • The inventory consists of a single contiguous IPv4 block (195.3.212.0/22) and one IPv6 prefix, representing a compact and unified corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
