AS8823 announces 14 IPv4 prefixes covering 45,824 addresses and 5 IPv6 prefixes.

About this network

AutonomousSystemRockensteinAG is rockenstein AG, a Würzburg-area Internet service provider and data-centre operator. It sells connectivity, colocation, managed servers, IP telephony and IT security to business customers, and traces its lineage back to a 1987 bulletin-board system.

What it's used for

Business connectivity and hosting. The sampled reverse DNS is a mix of the provider's own infrastructure and named customer systems: mail2.rox.net (rockenstein's own long-standing domain, also home to its ns1/ns2 nameservers), install.wesroc.de, fleet.cargorent.eu — a vehicle-fleet application — and dsl-net-hk.hk.mailbox.de. Named corporate hostnames on provider-announced space, with no dyn-, pppoe- or pool- subscriber naming anywhere in the sample. That is a B2B ISP and hosting network, not an eyeball network.

Notable

• About 48k IPv4 addresses across 14 prefixes plus 5 IPv6 prefixes. The inventory is scattered (77.76.192.0/18, 212.63.64.0/19, 213.214.0.0/19, 213.137.192.0/19, plus several /22s and /24s) but the blocks are ordinary German RIPE allocations carrying the operator's own and its customers' names — the untidiness of a thirty-year-old ISP, not of leased address space.
• 115 observed BGP neighbours — substantial peering for a regional provider, consistent with an operator that runs its own data centres and transit.

Interesting

The company began as the Happy-Rocky-Box, one of Germany's first dial-up mailboxes, started in the Upper Palatinate in 1987 and moved to Würzburg in 1990 when its founder went to study computer science there.
