About this network

NDGF is operated by NORDUnet, the Nordic University Network.

What it's used for

• The address space carries high-performance computing and research infrastructure, evidenced by reverse DNS entries such as dcache10.hpc.ku.dk, pool14.hpc.uib.no, and gauda.ndgf.org.
• The AS announces 960 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a dedicated research network rather than a commercial transit or access provider.
• Traffic consists of scientific data transfer, HPC cluster communications, and academic collaboration services within the Nordic region.

Notable

• Registrants for all announced prefixes are consistent with the announcer, listing NORDUnet NOC and Nordic University NOC.
• The address inventory is finely subdivided into specific functional blocks, including NDGF-CORE and NDGF-CENTERS, reflecting internal segmentation for different research centers.
