ProfHolod Ltd. holds AS210828, announcing the 158.255.75.0/24 prefix from its Shchelkovo manufacturing base. Public registry and routing evidence tie insulated panel and cold-storage door production to a visible internet footprint with two Russian upstreams. The profile establishes a monitoring baseline connectivity changes that could reflect business risk or regulatory exposure. Key uncertainties include the hosted services on the prefix, the absence of IPv6, and the non-confirmed nature of peering relationships. Watchpoints focus on registry updates, prefix stability, and upstream shifts.

Profholod ProfHolod Ltd.

ProfHolod Ltd. is a Shchelkovo-based manufacturer of insulated sandwich panels, PIR insulation boards, and cold storage equipment, with products sold in Russia and 27 countries. The company also operates autonomous system AS210828, announcing the IPv4 prefix 158.255.75.0/24, providing a public window into its digital connectivity and operational continuity.

Why It Matters

Monitoring AS210828's routing status and registry records provides early warning of disruptions that could affect ProfHolod's sales, logistics, and customer communication. A prefix withdrawal or upstream change could directly impact the company's international operations and serve as a broader indicator for Russian industrial internet users.

What Public Sources Show

ProfHolod Ltd., based in Shchelkovo, Moscow Region, is a manufacturer of insulated sandwich panels, PIR insulation boards, and cold storage doors, exporting to 27 countries. It also maintains a small but publicly visible internet presence through autonomous system AS210828 and the IPv4 prefix 158.255.75.0/24. This dual identity makes its routing footprint a useful indicator of operational health.

The RIPE NCC membership page lists ProfHolod at its Shchelkovo address. The company’s website details its product lines and its manufacturing site near Moscow, with an additional office in Yerevan, Armenia. IPinfo, BigDataCloud, and Cloudflare Radar all associate AS210828 with ProfHolod and show it announcing the single /24 prefix.

AS210828 connects the factory’s network to the internet via two upstream providers: AS8359 (MTS) and AS8641 (Nauka-Svyaz). This routing arrangement, visible in BGP data, lets the company serve its web presence and customer-facing tools. No IPv6 is currently advertised, limiting the footprint to IPv4.

Because ProfHolod relies on internet connectivity for sales and logistics across 27 countries, any disruption to its routing—such as a prefix withdrawal or upstream change—could directly impact business. For analysts, AS210828 acts as a digital canary: changes in its registry objects or BGP announcements may signal regulatory pressure, financial trouble, or strategic shifts.

The routing relationships are inferred from public BGP observation, not from commercial contracts. The specific applications hosted on 158.255.75.0/24 are not identified in public sources. Registry data was accessed via public mirrors, so some fields could be outdated. No downstream customers or peering arrangements are known.

Key watchpoints include any change in AS210828’s RIPE records, withdrawal or addition of IPv4 prefixes, appearance of IPv6, and shifts in upstream providers. Regular monitoring of prefix reachability and BGP updates can provide early warning of operational or regulatory changes affecting the company’s digital infrastructure.

Operating Surface

ProfHolod Ltd. serves as a Russian industrial manufacturer and a RIPE NCC member, holding AS210828 and the associated IPv4 prefix. Its internet infrastructure supports its web presence, including customer-facing tools, and its routing footprint allows monitoring of reachability and upstream dependencies via public BGP data.

The company's internet footprint, though small, is a publicly observable signal of its operational connectivity. Changes in registry records, prefix advertisements, or upstream peerings can indicate business continuity risks, regulatory exposure within the Russian telecom sector, or strategic shifts in digital infrastructure for an export-oriented manufacturer.

Watchpoints

ProfHolod Ltd. is a mid-sized Russian manufacturer whose digital footprint, though minimal, provides an observable bridge between physical operations and internet governance. Monitoring this footprint can yield early signals on the health of Russian industrial internet users under potential sanctions or regulatory pressure.

Key changes to watch: modifications to the AS210828 aut-num object, prefix announcements, upstream BGP sessions, and any new IPv6 allocations. A sudden drop in reachability or a change to a state-owned upstream would be a significant signal.

Direct RIPE Database access would provide more granular registry data. Hostname or service discovery on the /24 would clarify the applications dependent on the AS. Commercial agreements with upstreams are not publicly verifiable.
