What it's used for
- The address space carries corporate and enterprise infrastructure, evidenced by netnames such as
DE-SCZN-19920423andT-SYSTEMS-DTAG-T-SYSTEMSregistered to T-Systems International GmbH. - With 57600 IPv4 addresses and 103 observed neighbours, the inventory suggests a large-scale enterprise or service provider network rather than a simple transit provider.
Notable
- All registrants in the sample agree with the announcer, consistently listing T-Systems International GmbH.
- T-Systems is the IT services subsidiary of Deutsche Telekom, operating as a major enterprise IT provider.
- The address inventory is finely subdivided into numerous prefixes, including large blocks like 160.44.64.0/18 and smaller /24s, indicating site-by-site segmentation typical of a large corporate estate.

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 1,778 prefixes, as published 2026-10-20. 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.
