About this network

SICN belongs to Kertinis valstybes telekomunikaciju centras (KVTC), the Core Centre of State Telecommunications, a Lithuanian state institution on Gedimino Avenue in Vilnius.

What it's used for

• Operating Lithuania's Secure State Data Transmission Network, the government network that connects the country's most important institutions and is designed to keep working during crises, mobilisation or war, independently of public communications networks.
• Data-centre and telecommunications services for Lithuanian state bodies.

Notable

• Reverse DNS in the announced space resolves to Lithuanian public-sector hosts, including county administration mail servers under aps.lt, confirming that the addresses serve government users rather than a commercial customer base.
• KVTC is a budgetary institution under the Ministry of National Defence, formed out of the earlier state enterprise "Infostruktura", which had been the long-standing operator of Lithuania's government network. That lineage explains the low, early ASN.
