AS8904 BANK_OF_RUSSIA CBRF Autonomous System

BANK_OF_RUSSIA is the autonomous system of the **Central Bank of the Russian

Federation** (Bank of Russia), the country's monetary authority and banking

regulator.

What it's used for

• The central bank's own infrastructure and public presence. It is a state financial institution, so the space is classified government: there are no subscriber pools, no hosting estate and nothing sold to third parties.

Notable

• Small and tightly contained: about 5.9k IPv4 addresses across 5 prefixes, all inside the legacy 212.40.192.0/19 allocation, with only two observed BGP neighbours. That is a single institution buying transit, not a network with downstreams.
• No PTRs came back on the addresses sampled inside its prefixes. That is unremarkable for a closed institutional network and is not evidence about the zone's delegation one way or the other.

Interesting

• A central bank running its own AS since the late 1990s is less common than it sounds — most national banks of that era sat behind a state telco. The contiguous, unchanging 212.40.192.0/19 footprint suggests the network was designed once and left alone.
