Operated by Ferdinand Zink trading as Tube-Hosting, DE.
Summary
- // analyst note
- Small, actively-routed multi-tenant German budget host; attribute abuse to tenants, not the operator. Four Tor relays on this ASN's Dutch address space are middle relays, not exits — per-IP geolocation and attribution on this address space can still be unreliable. Allocation date, AS rank, customer cone size, RPKI validation, upstreams, and IX presence are Unknown.
- // security note
- NEUTRAL/DATED/SOURCED, multi-tenant budget host: CleanTalk shows spam-source activity concentrated on a small minority of IPs (11 of ~697 tracked, ~2.70% overall), first flagged November 2025 and active into August 2026, clustered in 3 prefixes at ~1.00% vs 0.00% elsewhere.
About this ASN.
AS49581 is an actively-routed German budget hosting and VPS network registered to Ferdinand Zink, trading as Tube-Hosting, headquartered in Bad Königshofen, Germany. As observed by RouteViews (route-views2 and route-views6 collectors) at 2026-08-15 02:00 UTC, it originates 36 IPv4 prefixes (9,216 addresses) and 3 IPv6 prefixes — a small, single-operator hosting network that is fully live, not dormant or legacy.
The operator runs a self-described budget, prepaid hosting business — vServer and VPS via LXC and KVM virtualization, KVM root servers, dedicated servers, and colocation — marketed on no-contract, prepaid terms. Its FAQ lists common customer workloads such as Minecraft and Teamspeak game servers, MySQL databases, and WordPress or Nextcloud installs, with DDoS protection bundled into every server at no extra cost. The company states it was founded in March 2015 and identifies itself as a RIPE NCC member (LIR).
Infrastructure sits at the SkyLink data center in Eygelshoven, Netherlands, which the operator describes as positioned between the DE-CIX and AMS-IX exchange regions with dark-fiber links to Frankfurt and Amsterdam, plus a public looking glass at lg.as49581.net. The same RouteViews snapshot recorded 85 distinct BGP neighbours, of which a 32-entry sample is listed below; AS_PATH adjacency carries no transit/customer direction, so specific upstream relationships, IX memberships, peering policy, RPKI validation, AS rank, and customer cone size are all Unknown.
Org status is active, with the operator's own site pages live and current as of an August 2026 review. The ASN's allocation date is Unknown, and no source establishes a related ASN under the same operator with confidence.
- Exposure
- Multi-tenant budget VPS/dedicated/colocation host — IPs are shared and rented, so abuse activity typically attaches to individual tenants rather than to the operator itself.
- Spam signal
- CleanTalk lists 11 currently spam-active IPs of roughly 697 tracked (about 2.70% overall), concentrated in three prefixes at about 1.00% versus 0.00% elsewhere, first flagged November 2025 and still active in August 2026 — cleantalk.org/blacklists/as49581.
- Tor relays
- Four Tor relays run on this ASN's Dutch address space, all classified as middle relays rather than exit relays as of an August 2026 check, first seen 2025-11-16 — nusenu.github.io/OrNetStats.
- Anonymity/P2P tags
- ipinfo.io's AS-level profile carries VPN and BitTorrent tags, consistent with anonymity- and P2P-adjacent tenant traffic on a budget VPS host — ipinfo.io/AS49581.
- Customer reviews
- Unverified, user-submitted Trustpilot reviews describe VPS suspensions over abuse complaints; in one thread the operator states a suspension followed a customer's own outbound "website attacks," i.e. its own enforcement action rather than an incident implicating the operator — trustpilot.com/review/tube-hosting.de.
- Negative checks
- No CVE, data breach, sanctions listing, law-enforcement seizure, or bulletproof-hosting/booter designation naming AS49581, Tube-Hosting, or Ferdinand Zink turned up in a search conducted in August 2026, and no NANOG mailing-list thread naming either turned up in the same search.
