MPWiK-WROC is the registry name for AS210262, owned by Wrocław's municipal water and sewage utility. The entity provides critical urban services while maintaining a direct internet routing presence. Evidence consists of RDAP registry records, BGP.Tools data, and the official company website confirming its utility role. No active BGP prefix announcements are currently observed, and no PeeringDB entry exists. The internal network architecture and OT/IT separation remain undisclosed. Watchpoints include registry record changes, new prefix announcements, and official website updates. The profile gives analysts a monitoring baseline dependency signals and network changes that may indicate operational or administrative shifts.

MPWiK-WROC

MPWiK-WROC is the RIPE NCC registry name for AS210262, a dormant autonomous system held by Wrocław's municipal water utility. It provides water supply and wastewater treatment for the city while maintaining this registered internet resource, making it both a critical infrastructure operator and a participant in the global routing system observable through public RDAP and BGP monitoring tools.

Why It Matters

As a city water and sewage utility, network disruptions could cause service outages, billing failures, or loss of operational telemetry, potentially affecting public health and safety. Even without active routing announcements, the existence of the registered ASN means any future BGP announcements or registry record changes may reveal a digital transformation or a security breach warranting investigation.

What Public Sources Show

MPWiK-WROC is the RIPE NCC registry name for autonomous system AS210262, assigned to Miejskie Przedsiębiorstwo Wodociągów i Kanalizacji S.A., the municipal water and sewage utility of Wrocław, Poland. The utility supplies drinking water, collects wastewater, and treats sewage for the city, relying on digital systems for operations and customer service.

Although the ASN currently broadcasts no BGP prefixes, its registration places the utility within the global internet routing framework and creates an externally observable anchor for monitoring its network activity.

The dormant ASN matters because it represents a potential entry point for network risk. If the utility activates BGP announcements, it will expose internal IP space to routing threats and increase its dependency on internet infrastructure. Even without active routing, the ASN’s registry records are public surfaces that, if altered maliciously or inadvertently, could misrepresent the utility’s digital identity or signal an administrative change.

For a critical service provider serving a major city, such changes can have cascading effects on water supply continuity and public confidence.

Public records confirm the assignment. The RIPE RDAP database at rdap.db.ripe.net shows AS210262 under the name MPWiK-WROC, with a country code for Poland. BGP.Tools corroborates the assignment and indicates no active prefixes. The utility’s official website, mpwik.wroc.pl, details its role in water and wastewater management for Wrocław. Additionally, RIPEstat provides an operational overview of the ASN.

Together, these sources establish the link between the ASN and the utility, and the dormant routing state.

The primary control surfaces are the RIPE NCC registry objects for AS210262—the aut-num, organisation, and abuse-contact records. Modifications to these records can be made by the holder and would change how global routing systems perceive the entity. The utility’s corporate website at mpwik.wroc.pl acts as a secondary surface, conveying its municipal services, announcements, and contact information.

No PeeringDB entry exists, and no upstream or peer relationships are publicly identified, limiting the visible operating surface to the ASN registration and the web presence.

Observers should monitor three areas. First, any change to the ASN’s registry records—contact details, organisation, or name—may indicate an administrative transfer, ownership change, or compromise. Second, the appearance of BGP prefix announcements would shift the ASN from dormant to active, introducing new risk surfaces and possibly revealing internal network addressing.

Third, sudden alterations to the utility’s website, such as the removal of service pages or unexpected downtime, could signal a cyber incident or operational disruption.

Significant gaps remain. The utility’s internal network architecture, including the separation between information technology and operational technology systems, is not publicly documented. No PeeringDB entry exists, leaving peering relationships invisible. The association between the ASN registration and the municipal company is based on name matching—no legal filing or corporate record explicitly confirms the link.

The absence of active BGP announcements also means the purpose of the ASN—whether legacy, future-use, or internal routing—is speculative.

For the city of Wrocław, digital failures in water services could have immediate public health and safety consequences. The publicly recorded ASN acts as an external indicator: changes to its registry records or the appearance of BGP announcements could signal either a planned digital transformation or a security incident requiring investigation. Monitoring these signals helps assess the utility’s cyber posture without access to its internal networks.

Operating Surface

The organisation is the primary water and sewage utility for Wrocław. Its public role encompasses drinking water production, distribution, wastewater collection, and treatment. On the internet side, it holds a registered but dormant autonomous system (AS210262) with no currently advertised prefixes, creating an external observation point for its network posture.

MPWiK-WROC is tracked because digital disruptions affecting its network administration or registered internet resources could cascade to customer portals, billing systems, and possibly operational technology networks supporting water supply. The publicly recorded ASN provides an externally visible indicator of that dependency, enabling monitoring of registry changes or new routing activity that may signal operational stress or security incidents.

Watchpoints

MPWiK-WROC exemplifies a critical service provider with a dormant digital footprint. The ASN registration provides a low-cost monitoring signal; changes there are proximal indicators of network activity that could prefigure operational risk. The lack of active routing restricts the surface today, but also means any future activation would be a notable shift. Monitoring this entity tests the thesis that non-ISP critical infrastructure can be tracked via their RIR registry artifacts.

Watch for modifications to the AS210262 aut-num, organization, or contacts in the RIPE database. Appearance of any BGP prefix announcements would change the entity's risk profile materially. Updates to the mpwik.wroc.pl website that reference network services, outages, or IT reorganization would be high-signal. Establishment of a PeeringDB entry would indicate a maturing interconnection strategy.

Missing: internal network architecture details, OT/IT separation, and the specific purpose of the ASN. No public financial data ties the ASN to budget for digital infrastructure. Confirmation via Polish corporate registry (KRS) that the ASN is formally assigned to the utility would strengthen the identity link. Direct interviews with utility IT managers or regulatory filings could fill the governance gap.
