About this network

A regional provider for northern Bavaria, based in Nuremberg.

What it's used for

• Access and business connectivity. 15,360 addresses over nineteen prefixes, six observed BGP neighbours, and three IPv6 announcements including a /29.

Notable

• Reverse DNS carries the medium and the location: odsl0255.odn.net for DSL lines, cust-apc04.odn.de for customer equipment, and c7-6.nbg.odn.net for a core device, where nbg is Nuremberg.
• One sampled address answers as fwmgmt.kicker.de — a firewall management interface for kicker, the German football magazine, published in Nuremberg.
• The netnames split the inventory in two: everything in 212.34 is DE-ODN-990329, everything in 86.109 is DE-ODN-20050712. Two allocations, six years apart.
• The registry's AS handle field holds a street address, Hermann-Glockner-Str. 7, rather than a description.

Interesting

• A magazine's firewall inside a regional ISP's address space is what local providers were for. A publisher in Nuremberg bought its connectivity from a company in Nuremberg, and twenty-odd years later the equipment is still there and still named after the job it does.
• Nordbayern is a region, not a city, and naming a company after one is a claim about territory. This is the second Nuremberg network in this range with a deep address history, alongside noris network at AS12337.
