Summary

Westfalen-Informatik AG

Germany · AI-generated

business it-services germany

The AS handle WESTFALEN-INFORMATIK is held by Westfalen-Informatik AG.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by the netname DE-WESTFALEN-INFORMATIK-20260316 and registrant Administration; Westfalen-Informatik AG.
  • The network announces 256 IPv4 addresses in a single /24 prefix and one IPv6 prefix, with only one observed neighbour, indicating a small, self-contained internal estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and IT services for Westfalen-Informatik AG, a German IT services company based in Dortmund.

Notable

  • The RDAP registrant Westfalen-Informatik AG matches the AS holder and the netname, confirming consistent ownership.
  • The address inventory is minimal, consisting of a single IPv4 /24 and one IPv6 /29, typical of a small corporate network.

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: 445 networks and 1,817 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.
