About this network

OSN is OSN Online Service Nürnberg GmbH, a Nuremberg internet service provider and hosting company that has been operating since the mid-1990s. It sells server housing, virtual servers, IT outsourcing, connectivity and VPN services to German businesses.

What it's used for

• Hosting and managed infrastructure. The sampled reverse names are first-party across the board: cloud01.osn.de, dns.osn-cdn.net, generic address names in ip-IP-ADDR.osn.de, customer space in cust.osn.de, and routers such as ha-gw-vl10.nbg1.osn.net.

Notable

• Roughly 26k IPv4 addresses across five prefixes, but around 94 observed BGP neighbours — a peering profile much larger than the address count implies. That gap is typical of a well-connected regional host sitting on German exchanges, and it is why neighbour count is a better size signal than address count.
• No IPv6 is announced, which is unusual for a hosting provider of this age.

Interesting

• One of the announced prefixes, 193.17.21.0/24, resolves to gofw.nbg.de — the reverse zone of the city of Nuremberg. OSN appears to route address space for its municipal outsourcing customer, so a name inside this AS may belong to the city rather than to the hosting company.
