AS12337 NORIS-NETWORK IT Service Provider located in Nuernberg, Germany
Unclassified RIPE NSP
Summary
noris network AG
hosting datacenter business legacy
A Nuremberg IT service provider running its own datacentres and selling managed infrastructure, colocation and connectivity to German businesses.
What it's used for
- Hosted and managed infrastructure. 114,944 addresses across 78 IPv4 prefixes, with 144 observed BGP neighbours.
Notable
- 144 neighbours is the figure that describes this network. Against 115,000 addresses that is an interconnection-heavy profile: a provider that peers widely so its hosted customers reach German networks directly.
- The IPv6 inventory runs deeper than the IPv4 one runs wide. Twenty-seven prefixes, most of them nested under
2001:780::/34— a/36, a/39, a/40, a/46, a/47and a/48all announced alongside the block that already contains them. - Three further IPv6
/48s come from2001:67c::/32, the range RIPE keeps for provider-independent assignments and exchange point peering LANs, rather than from the provider's own allocation. - The netnames date the buildout:
DE-NORIS-990421on the oldest/19, thenDE-NORIS-20000117,DE-NORIS-20000403andDE-NORIS-20000914inside a single year, andDE-NORIS-20060810.
Interesting
- Noris is the poetic Latin name for Nuremberg, used on the city's coats of arms and monuments for centuries. The company named itself after its city, and did it in the register as well: every netname in the inventory begins
DE-NORIS. - Nuremberg is the second cluster of German hosting after Frankfurt, and it got there without an exchange the size of DE-CIX. What it has instead is cheap power, room to build and a location roughly in the middle of the country, which is the same argument that put several much larger hosting operations within an hour's drive.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
