Summary
Northern Data
hpc datacenter gpu ai
NORTHERNDATA is operated by Northern Data AG.
What it's used for
- The address space carries high-performance computing and data center infrastructure, evidenced by the reverse DNS record
ens192.e8dba12b-1799-46c4-a680-74733d7d78d8.hydro66.northerndata.techand netnames such asDE-NORTHERNDATA-20110530. - The AS announces 14848 IPv4 addresses across 19 prefixes and 7 IPv6 prefixes, while maintaining 108 observed neighbours; this ratio indicates a large-scale infrastructure provider with significant peering relationships rather than a residential access network.
- Traffic from this AS consists of GPU infrastructure for high-performance computing, artificial intelligence workloads, and blockchain mining, reflecting Northern Data's business as a provider of sovereign AI cloud and HPC solutions.
Notable
- Registrants for the majority of prefixes are listed as "Network Management Center; Northern Data Software GmbH", which aligns with the AS holder Northern Data AG, while several smaller prefixes (e.g., 85.234.66.0/23) are registered to G-Core Labs S.A.
- The address inventory is a mix of large blocks like 176.56.192.0/20 and numerous /24s, with some space historically associated with G-Core Labs, suggesting a consolidated infrastructure estate.

Reputation
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 1,779 prefixes, as published 2026-10-22. 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.
