About this network

SigmaNet-NIC is SigmaNet, Latvia's national research and education network, run by the Academic Network Laboratory of the Institute of Mathematics and Computer Science at the University of Latvia (IMCS UL) in Riga.

What it's used for

• Connecting Latvian universities, research institutes, and other academic bodies to each other and to the pan-European research network GÉANT.
• Supporting services for the academic community: hosting, e-mail, and data-centre resources.

Notable

• This is an NREN, so the address space serves institutions and researchers rather than paying consumers. Traffic patterns look like campus and research traffic, not eyeball broadband.
• IMCS UL is the umbrella for several pieces of Latvian internet infrastructure, operating publicly under the SigmaNet, CERT.LV, and domain-registry (NIC) brands. Address space here can therefore carry national-scale infrastructure roles as well as campus networking.

Interesting

• The network began operating in 1992 under the name LATNET, making it one of the first internet networks in the newly independent Baltic states. It was renamed SigmaNet in 2008.
