Serverhino Netversor GmbH operates the Serverhino hosting brand under Netversor GmbH, using AS210819 and two prefixes as its sole public routing surface. Evidence from official sites, registry mirrors, and dashboards confirms identity and basic network posture but leaves revenue, customer counts, and exact data-centre locations unknown. The SIM-Networks maintainer hints at a wider group linkage without independent verification. Watchpoints include RIPE object modifications, prefix withdrawal, corporate register changes, and website availability. Live BGP data must be confirmed before operational action.

Serverhino Netversor GmbH

Serverhino Netversor GmbH is the public hosting brand of Netversor GmbH, a German company registered in Karlsruhe. It markets virtual private servers, dedicated hardware, backup, SSL certificates, and software licences with 24/7 support. Its internet delivery is entirely dependent on AS210819 and two prefixes, creating a concentrated operational risk and a sharp monitoring signal for analysts tracking small hosting providers.

Why It Matters

If AS210819 withdraws its BGP announcements or if its upstream transit providers stop accepting its routes, all hosted services relying on Serverhino's infrastructure would lose internet connectivity. Downstream tenants and resellers, if any, would also be affected. Conversely, a new prefix or upstream would expand its service delivery surface.

What Sources Show

Serverhino is the public hosting brand of Netversor GmbH, a German company registered in Karlsruhe (HRB 720562 Mannheim, VAT DE 815 526 143) with CEO Sergey Stark. It sells virtual private servers, dedicated hardware, backup, SSL certificates, and software licences, marketing 24/7 support and self-described Tier-III+ data-centre positioning.

The brand’s entire internet delivery surface is AS210819, which originates the IPv4 prefix 92.246.88.0/22 and the IPv6 prefix 2a0e:4006::/32. Because there is no evidence of alternative routing or backup connectivity, any withdrawal of those prefixes or failure of its two listed upstreams—AS9002 and AS3356—would sever all hosted services from the internet, making the company a concentrated operational risk and a useful monitoring target.

Public registry mirrors show AS210819 was allocated in September 2021 and lists upstream imports from RETN (AS9002) and Lumen (AS3356). Cloudflare Radar groups the ASN with AS200081 (SIM-Networks) and AS201492 (Netversor-4), suggesting a wider organisational cluster. RIPE whois records a maintainer reference of SIMNETWORKS-MNT, which hints at a sibling operation, though no separate company registration for SIM-Networks has been located in the supplied evidence.

The operating surface is narrow: AS210819, its two prefixes, and the operator-controlled websites serverhino.com and netversor.com. The imprint pages on both sites confirm the Karlsruhe address, CEO, and commercial register details. No PeeringDB entry, no separate network presence, and no alternative transit providers are apparent from the evidence, leaving the hosting service dependent on a single ASN.

If routes for 92.246.88.0/22 or 2a0e:4006::/32 are withdrawn, or if the upstream providers stop accepting announcements from AS210819, every hosted website and application reliant on Serverhino’s infrastructure would lose connectivity. The company’s thin footprint amplifies the disruption risk.

modifications to the RIPE aut-num or route objects—new upstreams, withdrawn prefixes, altered maintainer references—would directly change the operating surface. Changes to the German commercial register (CEO, office, business purpose) could signal strategic or ownership shifts. The disappearance or defacement of serverhino.com or netversor.com would reduce transparency and may indicate operational failure. Live BGP data should be checked regularly.

Key uncertainties: the direct RIPE Database REST output was not retrieved; registry facts rely on public mirrors. Customer counts, revenue, exact data-centre locations, and any private peering are unknown. The SIMNETWORKS-MNT maintainer suggests a connection to SIM-Networks, but no independent company record has been found. All routing statistics should be treated as time-sensitive and reconfirmed close to publication.

Operating Surface

Serverhino Netversor GmbH operates as a low-cost hosting provider under the Serverhino brand, with AS210819 originating IPv4 and IPv6 prefixes from upstreams AS9002 and AS3356. Its public role is that of a small digital infrastructure operator whose service availability is directly tied to a single autonomous system number and a narrow set of routing announcements.

Tracking Serverhino Netversor GmbH matters because its entire customer-facing hosting service depends on a single ASN and just two prefixes. Any routing change, prefix withdrawal, or upstream disruption can immediately sever internet connectivity for all hosted websites and applications, making it a reliable early-warning signal for internet infrastructure analysts monitoring small hosting provider health and dependency chains.

Watchpoints

Serverhino Netversor GmbH represents a fragile infrastructure node: a commercial hosting brand with no observable redundancy. Strategic interest lies in its dependency on two upstreams and the possible sibling link to SIM-Networks. Its stability is a barometer for small RIPE-region LIRs, and any change in its routing surface signals operational or commercial realignment that could affect downstream customers.

Monitor RIPE aut-num and route objects for modifications, especially changes to upstreams, prefix origin, or maintainer. Track BGP announcements via RIS/route-views. Watch serverhino.com and netversor.com for reachability. Check German commercial register (HRB 720562) for changes to managing director or business purpose.

Direct RIPE Database REST output not confirmed. No PeeringDB or IRR data found. Customer counts, revenue, actual data centre facilities and contracts are unknown. The relationship between Netversor GmbH and SIM-Networks is conjectural based on a maintainer reference; independent verifiable evidence is needed to assert a sibling organisation.
