Summary

MSH Medien System Haus

Germany · AI-generated

hosting business media

A block whose contact and registrant differ by a letter transposition: MSH against MHS.

What it's used for

  • Media and systems hosting in Germany. 15,872 addresses in five IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

  • 195.238.128.0/19 is netname DE-MSH-970102, dated the second day of January 1997.
  • Three blocks share DE-MSH-990923: 212.4.224.0/20, 212.4.244.0/22 and 212.4.248.0/21.
  • 195.191.42.0/23 is netname SIR-NET, registered to MHS Digital GmbH with MSH Hostmaster as its contact.
  • Fifteen sampled addresses were queried and none returned a name.

Interesting

  • MSH and MHS on the same record, one as the contact and one as the registrant, differ only in the order of two letters. Whether that is a rebrand, a related company or a typing slip is not something the registry can answer, and either way both spellings are now official. Three letters in a different order is exactly the kind of difference that automated matching gets wrong in both directions.
  • The January 1997 date is among the oldest here, and the second of January is a working day chosen by whoever came back from the holidays with a form to file.
  • Three separate announcements out of 212.4.0.0 sharing one netname and one date is the same pattern that shows up repeatedly in this range: the split happened after the allocation, for internal reasons, and every router on the Internet carries the result.

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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
