AS8240 AS8240 RIA Autonomous System

AS8240 RIA Autonomous System belongs to the Riigi Infosüsteemi Amet (RIA), the Estonian Information System Authority — the state agency that runs Estonia's central digital-government platforms and its national cyber-security centre.

What it's used for

• Carrying the Estonian state network (the government backbone historically operated under the ASO name), which interconnects ministries, agencies and public bodies.
• Roughly 18,000 IPv4 addresses across a handful of prefixes, plus IPv6.
• Reverse DNS on the routed space lands on aso.ee — backbone-router names of the form cr1-bb18-vNNN.aso.ee and ncs1-bb2-vNNN.aso.ee. That is state network infrastructure, not consumer or hosting space.

Notable

• Addresses here should be read as Estonian government, not as a commercial ISP. RIA also operates the national CERT (CERT-EE) and the X-Road data-exchange layer that underpins Estonia's e-government services.
• The agency's remit spans both running the network and defending it, so the same AS fronts routine public-sector traffic and the state's security functions.
