Unclassified RIPE Enterprise
Summary
ITSG
government healthcare it business
AS-ITSG is held by ITSG Informationstechnische Servicestelle der Gesetzlichen Krankenversicherung GmbH.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by netnames
DE-ITSG-20190926,DE-ITSG-20180323, andITSG-NETall registered to ITSG. - The AS announces 2304 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, while maintaining 27 observed neighbours; this ratio of modest address space against a significant number of peering partners indicates a transit or interconnection role rather than a large-scale access network.
- Traffic from this AS consists of IT services and digital communication infrastructure supporting the German statutory health insurance system, including web endpoints and internal application backends for social insurance institutions.
Notable
- All registrants for the announced prefixes agree with the AS holder, listing ITSG Informationstechnische Servicestelle der Gesetzlichen Krankenversicherung GmbH.
- ITSG serves as the dedicated IT service provider for the German healthcare and social welfare sector, developing and operating applications for digital communication within the statutory health insurance system.
- The inventory is finely subdivided into three distinct IPv4 blocks and two IPv6 prefixes, consistent with an internal corporate estate segmented by function or site.

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.
