FIVE CYBER HOST SECURITY S.R.L. operates AS210718, a RIPE-region autonomous system originating two prefixes and buying transit from DIGI ROMANIA S.A. and Internet Magnate (Pty) Ltd. Public sources confirm registry identity and company registration under CAEN 6311, but no revenue, customer, or leadership data is available. The profile is useful for monitoring routing dependencies and low-scale hosting exposure; actual business scale is unverifiable. Watchpoints include registry changes, prefix announcements, and the emergence of a live website.

FIVE CYBER HOST SECURITY S.R.L.

FIVE CYBER HOST SECURITY S.R.L. is a Romanian registered company that holds AS210718 and two IP prefixes, yet its actual business operations remain invisible beyond RIPE registry and BGP routing data. The entity’s public footprint is limited to an open peering policy and a non-resolving domain, raising questions about its active hosting activities.

Why It Matters

Routing changes, prefix withdrawals, or misconfigurations for AS210718 would directly impact reachability of services hosted on its IP space. Its reliance on two transit providers creates a dependency chain where upstream disruptions in Romania or South Africa could cascade to customers.

What Public Sources Show

FIVE CYBER HOST SECURITY S.R.L. is a Romanian limited liability company that holds autonomous system number AS210718 and two IP prefixes, yet almost nothing else about its operations is publicly visible. Registered under fiscal code CUI 41758330 in Teleorman county, the company lists its primary activity as data processing and web hosting (CAEN 6311), but no customer website, service catalog, or revenue data has ever been identified.

Its entire public footprint reduces to a handful of RIPE registry entries and BGP routing announcements.

AS210718 was established in September 2021 and currently originates the IPv4 prefix 93.115.101.0/24 and the IPv6 prefix 2a0f:9400:7e01::/48. The autonomous system buys transit from two upstream providers: DIGI ROMANIA S.A. (AS8708), a major Romanian telecommunications operator, and Internet Magnate (Pty) Ltd (AS214209), a South Africa-based transit seller. PeeringDB records an open peering policy, but no listed peers, and the IRR as-set RIPE::AS-FIVE-CYBER-HOST-SECURITY manages routing filtering.

Multiple data sources—RIPE Stat, Cloudflare Radar, BGP.tools, IPinfo, and IPLocate—agree on this basic network picture. The RIPE aut-num object, maintained by FIVE_CYBER_HOST_SECURITY-MNT, was last updated in November 2025 and includes the domain five-host.com as a remark. However, that domain does not resolve to any live website, and no archived copy reveals past service offerings.

The Romanian business directory Listafirme.ro confirms the company’s legal existence and registration number J34/574/2020, but no financial filings or press coverage are available to judge its economic substance.

Because the company’s entire operational control surface is limited to its RIPE records and BGP announcements, any change to these digital artifacts immediately alters its network posture. The organisation holds the maintainer password for MNT-FIVE_CYBER_HOST_SECURITY, owns the PeeringDB entry for AS210718, and controls the DNS zone for five-host.com.

In practice, the ability to modify IRR route objects or renumber the ASN constitutes the company’s sole observable authority; there is no evidence of a physical office, staff, or technical team.

The real-world consequence is that any routing misconfiguration, prefix hijacking, RPKI failure, or upstream disconnection could silently disrupt whatever services are hosted on 93.115.101.0/24 or 2a0f:9400:7e01::/48. Because no customer roster exists, the blast radius is unknown: a single web application, a provider’s DNS resolver, or a block of virtual servers could vanish from the public internet without warning.

This dependency chain concentrates risk in two upstream providers that have no obligation to disclose private customer incidents.

Observers should watch for three signals: first, any modification to the RIPE aut-num, organisation, or maintainer records for AS210718, which could indicate a transfer or abandonment; second, the addition or withdrawal of prefixes, which would expand or shrink the infrastructure surface; and third, the sudden appearance of a functioning company website or financial report, anchoring commercial assessment.

Until such evidence emerges, the entity remains a registry-confirmed shell whose true activity is concealed behind an open peering policy and a non-resolving domain.

The core uncertainty is whether FIVE CYBER HOST SECURITY S.R.L. actively sells hosting or merely parks internet number resources. The company’s address in a small Teleorman locality and the absence of any LinkedIn or job posting activity suggest extremely limited operations.

Future collection should monitor Romanian corporate registry updates, BGP tables for new announcements, and WHOIS changes for any named contact, which would be the earliest sign that real business activity is underway.

Operating Surface

As the registrant of AS210718 and two IP prefixes, FIVE CYBER HOST SECURITY S.R.L. controls a small autonomous system that buys transit from DIGI ROMANIA S.A. and Internet Magnate (Pty) Ltd. Its public operating surface is confined to RIPE records and BGP announcements; no service catalog, customers, or revenue stream has been identified.

Changes to AS210718 routing, RPKI state, upstream dependencies, or prefix advertisements could directly affect reachability of any services hosted on its IP space. Monitoring this entity helps map infrastructure dependencies and detect potential single points of failure in niche hosting supply chains within Romania.

Watchpoints

This entity is a minimal internet-number resource holder with no visible commercial activity. Its network dependency on two transit providers creates a small but non-zero risk concentration. In its current opaque state, it represents an infrastructure shell that could be activated or abandoned without market notice.

Monitor RIPE WHOIS updates for maintainer or org-handle changes, BGP announcements for prefix additions/withdrawals, PeeringDB policy updates, and the resolution status of five-host.com. Any new PeeringDB peer records or a live website would signal operational expansion.

No active company website, financial filings, or customer references exist. Official Romanian trade registry confirmation beyond Listafirme.ro is missing. Named contacts or staffing information is absent. Verifying physical office presence and obtaining customer testimonials would reduce uncertainty.
