About this network

UARNET-AS is UARNet, the Ukrainian Academic and Research Network, based in Lviv. The registry holder of record is LLC Eksintech, the company that operates the network today; the registry description still carries both the UARNet name and the older EARN-Ukraine reference.

What it's used for

• Connectivity for Ukrainian universities, institutes and research organisations, with UARNet acting as the academic network operator for the Lviv region and beyond.
• Commercial internet access alongside the academic role, which is common for research networks that grew into general-purpose providers.

Notable

• This is largely an institutional address: campuses, faculty networks and research systems, so much of the traffic from it is university rather than consumer.
• It buys transit from several tier-1 carriers, which gives an academic network in a mid-sized city surprisingly good international reach.

Interesting

• The EARN-Ukraine fragment in the registry description points at EARN, the European academic networking effort that predated widespread commercial internet in the region. The ASN is a direct descendant of that lineage.
