Summary

INSIGMA IT Engineering GmbH

Germany · AI-generated

business it-services germany

The AS handle INSIGMA1 is held by INSIGMA IT Engineering GmbH.

What it's used for

  • The space carries corporate IT infrastructure, evidenced by the netname INSIGMA-1 and the reverse DNS entry continentale.aktuarmed.de.
  • The network announces 512 IPv4 addresses within a single prefix (91.226.162.0/23) and maintains one observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and IT services provided by the company to its clients, consistent with its business model of developing IT solutions for mid-sized enterprises and corporations.

Notable

  • Registrants align with the announcer, listing INSIGMA IT Engineering GmbH alongside administrative contacts for NetCologne.
  • The address inventory is compact, consisting of a single /23 block in Germany, which fits the profile of a specialized IT engineering firm rather than a large-scale ISP.

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.
