Summary
ITZBund
government it federal infrastructure
The AS handle ITZBUND is operated by ITZBund (Informationstechnikzentrum Bund).
What it's used for
- The address space carries federal government IT infrastructure, evidenced by the reverse DNS record
sec.gss.bmwk.bund.deand netnames likeITZBUND-NET-1. - The AS announces 4096 IPv4 addresses across 7 prefixes and 11 IPv6 prefixes, while maintaining 85 observed neighbours; this ratio of moderate address space to high connectivity suggests a central hub role for federal data exchange rather than a simple access network.
Notable
- All registrants for the announced IPv4 prefixes are listed as "ITZBund LIR Administration Team; Abuse-C Role", which aligns perfectly with the AS holder.
- ITZBund serves as the central IT service provider for the German Federal Government, managing critical processes for ministries including transport, budget, and internal security.
- The inventory consists of a contiguous block of /22 and /23 prefixes in the 80.245.144.0/20 range, alongside a large, finely subdivided IPv6 allocation starting at 2a09:1480::/39.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
