Summary

Datahaus GmbH

Germany · AI-generated

business germany small

The AS handle DATAHAUS is held by Datahaus GmbH.

What it's used for

  • The address space carries a single IPv4 prefix, 31.25.48.0/21, with the netname DE-MEDIABEAM-20110302 and registrant listed as "IT Administration; Datahaus GmbH".
  • The inventory consists of 2048 IPv4 addresses across 1 prefix, with 0 IPv6 prefixes announced.
  • With only 2 observed neighbours, the low neighbour count relative to the address block suggests a small-scale internal or business network rather than a transit or large access provider.

Notable

  • The registrant "IT Administration; Datahaus GmbH" aligns with the AS holder Datahaus GmbH.
  • The netname DE-MEDIABEAM-20110302 indicates the address space was originally allocated to Mediabeam in 2011, suggesting a history of address space transfer or acquisition prior to the current holder.
  • The address inventory is a single contiguous /21 block, indicating a simple and compact allocation.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
