Summary

STACKIT

Germany · AI-generated

cloud colocation business infrastructure

The AS handle SCHWARZ-IT is held by INTAC Services GmbH, the IT services division of the Schwarz Group.

What it's used for

  • The address space carries internal corporate infrastructure and cloud services, evidenced by netnames such as SIT-COLO-INFRA and CLOUD-SVC-NET48-49.
  • The AS announces 48384 IPv4 addresses across 16 prefixes and 4 IPv6 prefixes, while maintaining only 2 observed routing neighbours.
  • This high address-to-neighbour ratio indicates an internal corporate estate rather than a transit or access network, consistent with the finely subdivided inventory used for site-by-site segmentation.

Notable

  • Registrants for the majority of prefixes are listed as INTAC Services GmbH, aligning with the AS holder, while some smaller blocks are registered under Abuse-C Role.
  • The operator is known commercially as STACKIT, a brand associated with the Schwarz Group's cloud and IT services.
  • The inventory includes legacy prefixes dating back to 1988, such as 9.204.8.0/21, alongside more recent allocations from 2019.

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.
