ERTH-CITY JSC "ER-Telecom Holding" is a Russian telecommunications operator tracked through its active AS9049 and dormant AS210766 autonomous systems. Public registry, routing, and domain evidence shows a company with a 100,000+ km fiber network serving over 15 million households under the Dom.ru brand. The profile is limited to public operating surface: no named executives, no verified commercial metrics. Its value lies in monitoring for prefix changes, AS activation, or record updates that could signal operational shifts. All claims rely on open-source intelligence and should not imply knowledge of private contracts.

ERTH-CITY JSC "ER-Telecom Holding"

JSC "ER-Telecom Holding" is a Russian telecommunications operator with a visible public footprint in RIPE registry records, BGP announcements, and the Dom.ru consumer broadband brand. Evidence shows it operates an active carrier autonomous system (AS9049) and holds a dormant one (AS210766). The company claims over 15 million households served and a 100,000-kilometer fiber network.

The profile is based on open-source data and does not infer private contracts or named executive control.

Why It Matters

If AS210766 becomes announced, AS9049 changes its upstreams or prefixes, or registry records are modified, it can affect how network operators assess exposure to Russian infrastructure. Observable shifts in this operator's public surface offer a concrete, low-latency signal for connectivity risk assessments and route-policy adjustments.

What Sources Show

JSC "ER-Telecom Holding" is a Russian telecommunications and digital infrastructure operator whose public network surface offers a concrete monitoring point for connectivity shifts. Through the active carrier autonomous system AS9049, it originates IPv4 and IPv6 prefixes and peers with multiple upstream carriers.

The company also holds the dormant AS210766, registered under the as-name ERTH-CITY, and operates the consumer broadband brand Dom.ru, which by its own account reaches over 15 million households over more than 100,000 kilometers of fiber.

Tracking this organization matters because changes in its BGP announcements, registry records, or domain infrastructure can signal operational or regulatory shifts in Russian internet connectivity before formal filings appear. Activation of the unused AS210766, a sudden withdrawal of prefixes from AS9049, or modifications to its RIPE LIR records would each be an observable event that could force dependency reviews and route-policy adjustments for networks that interconnect with Russian infrastructure.

JSC "ER-Telecom Holding" functions as a Local Internet Registry under the RIPE NCC, allowing it to manage its own IP resources and autonomous systems. Public records show that the organization has been active since at least 2001 and provides broadband internet, telephony, digital television, Wi-Fi, VPN, LoRaWAN-based services, video surveillance, intercom systems, and industrial IoT solutions.

The corporate domain ertelecom.ru and the consumer-facing dom.ru, registered as early as 1996, rely on the operator’s own nameservers.

The operating surface that can be watched without private access includes the RIPE database objects for ORG-RA21-RIPE, AS210766, and AS9049; the live BGP announcements from AS9049; and the DNS infrastructure behind ertelecom.ru and dom.ru. Together these provide a public control panel: changes in the aut-num records, new prefixes announced or withdrawn, and alterations to the organization’s name-server assignments are all visible to any network observer.

Concrete watchpoints include the first BGP announcement of prefixes by AS210766, which would mark a shift from a dormant reservation to an active routing role. Analysts should also monitor changes in the upstream peers of AS9049, the addition or removal of IPv4 and IPv6 prefixes under either ASN, and any updates to the RIPE administrative or technical contacts.

Modifications to the Dom.ru domain registration or its name servers are likewise relevant, as they can reveal administrative or structural changes at the holding-company level.

The evidence behind this profile comes from RIPE registry mirrors, routing analytics platforms, the company’s own careers website, a TCI WHOIS mirror for dom.ru, and a Russian news report. AS210766 is currently listed as inactive with no announced prefixes, and third-party sources differ on whether it controls any IP space, a gap that should be resolved through direct RIPE Database queries and live BGP collectors.

No named executives or staff are publicly linked to the autonomous systems, so accountability mapping remains limited to corporate and registry handles.

The self-published scale figures—15.1 million households in network, 9,000-plus employees, and over 100,000 km of fiber—come from the company’s recruitment portal and have not been independently verified. Until routing evidence for AS210766 solidifies or named individuals appear in public records, the assessment is bounded by observable numbering and domain data.

Still, these public signals offer a low-latency way to detect infrastructure shifts in a part of the internet that is otherwise opaque to external risk monitoring.

Operating Surface

As a Local Internet Registry (LIR) under RIPE NCC, JSC "ER-Telecom Holding" manages public IP resources and autonomous systems. It operates AS9049, an active carrier with multiple upstreams, and holds AS210766, a reserved but currently inactive autonomous system. Its public domains include ertelecom.ru and the Dom.ru consumer brand, which by the company's own account serves over 15 million households over a fiber network exceeding 100,000 km.

Changes in BGP announcements, registry records, or domain infrastructure for this operator can signal operational or regulatory shifts in Russian internet connectivity without requiring private contracts. Monitoring its public surface provides early warning of network-level changes that may affect dependency maps and risk assessments for Russian digital infrastructure.

Watchpoints

JSC "ER-Telecom Holding" represents a significant but not fully transparent node in Russian internet infrastructure. Its active AS9049 provides a live routing signal, while the inactive AS210766 offers a reserve of numbering capacity that could be activated for expansion or reorganization.

The operator's self-published scale and LIR status make it a useful proxy for monitoring Russian access and metro network shifts; changes in its public surface should be correlated with broader political or regulatory developments.

Watch for AS210766 obtaining and announcing live prefixes, which would indicate a new operational role. Changes in AS9049's upstream providers or sudden prefix withdrawals could signal peering disputes, network consolidation, or sanctions-related adjustments. RIPE contact updates would hint at administrative changes or new corporate affiliations. Domain transfers or name-server changes could reflect corporate restructuring.

The precise IP inventory of AS210766 is unconfirmed and should be validated against the RIPE Database and live BGP collectors. No named personnel are linked, limiting understanding of decision-making authority. The company's revenue model, customer contracts, and precise geographic coverage remain undocumented in public sources. Independent verification of the published household and fiber figures is lacking.
