Germany · AI-generated

isp business dsl legacy

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.

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 1,784 prefixes, as published 2026-10-19. 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.
