About this network

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 /47 and a /48 all announced alongside the block that already contains them.
• Three further IPv6 /48s come from 2001:67c::/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-990421 on the oldest /19, then DE-NORIS-20000117, DE-NORIS-20000403 and DE-NORIS-20000914 inside a single year, and DE-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.
