Summary

MCS GmbH

Germany · AI-generated

business germany small

MCS-AS is operated by MCS GmbH.

What it's used for

  • The space carries a single IPv4 block, 147.78.88.0/22, with netname DE-MCS-20190118 and registrant MCS GmbH.
  • The AS announces 1024 IPv4 addresses and 1 IPv6 prefix (2a09:2040::/29) while maintaining only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or large access provider.
  • As a business entity, the traffic consists of internal corporate communications and services for MCS GmbH.

Notable

  • The RDAP registrant MCS GmbH matches the AS holder and the netname registrant, confirming consistent ownership.
  • The address inventory is compact, consisting of one contiguous /22 block and a single /29 IPv6 prefix, typical of a small enterprise allocation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
