AS5589 — OPEN-FC-1-AS

AS5589 announces 13 IPv4 prefixes covering 4,096 addresses and 0 IPv6 prefixes.

About this network

OPEN-FC-1-AS is a Russian banking network. The handle stands for Otkritie Financial Corporation ("otkritie" means open, and the abuse contact is still [email protected]); Otkritie FC Bank was reorganised into JSC "BM-Bank" by accession at the start of 2025, and the RIPE registration follows the surviving entity.

What it's used for

Corporate infrastructure for a large Russian bank — internet-facing banking services, branch and office connectivity, and the network edge fronting its customer-facing systems. About 4,000 IPv4 addresses, small and purpose-built rather than a service-provider pool.

Notable

This is an end-user enterprise network, not a provider. Its upstreams are Russian incumbents — Rostelecom and VimpelCom — and the AS exists to multihome the bank's own address space rather than to sell connectivity to anyone else.

Interesting

The registry name lags the corporate reality by design: the OPEN-FC handle predates the merger, so a lookup shows the Otkritie-era identity attached to BM-Bank's org record. It is a good example of why an AS name should never be treated as the current legal holder.
