AS8648 ONE-NETWORK

dogado GmbH (ONE-NETWORK) — a Dortmund-based web-hosting and cloud group. The

AS carries the shared network for dogado and the many hosting brands the group

has acquired across Germany, Austria and Czechia.

What it's used for

• Shared hosting, managed servers and VPS. The rDNS is a tour of the group's brand portfolio: csNNNNN.dogadoserver.de, vpsNNNNN.alfahosting-vps.de, vpsNNNN.webglobe.com, hostingzdarma.cz, hosting90.net, cloud-anywhere.eu, busymouse24.de, mydhp.de — plus thousands of customer vanity names (mail servers, shop servers, small-business boxes).
• Its own backbone shows up under net.g1i.one (core1.fra.de…, edge1.lej.de…), tying the estate together through Frankfurt and Leipzig.

Notable

• On paper this looks like the address-broker silhouette: ~75 scattered prefixes, many of them lone /24s, spread across German, Czech and Ukrainian-registered ranges. It isn't. Every block carries first-party rDNS on a dogado-group brand, and the untidiness is the direct consequence of a decade of acquisitions — each absorbed hoster brought its own address space and its own reverse zone.
• Roughly 113,000 IPv4 addresses in total, which makes it one of the larger independent German hosting networks.

Interesting

• The naming convention is an acquisition archaeology record: you can read the group's M&A history off the reverse DNS without looking at a single press release.
