About this network

SOUTH-DAKOTA-RESEARCH-AND-EDUCATION-NETWORK is operated by the South Dakota Board of Regents.

What it's used for

• The address space carries infrastructure for South Dakota's higher education and state government sectors, evidenced by netnames SDSMTNET (South Dakota School of Mines & Technology), SDNET-BLK2-0-15 (University of South Dakota), DDNNET-BLK-2 (South Dakota State Government), and NET-SDNET-BLK2-18 (South Dakota Board of Regents).
• The AS announces 2048 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 11 observed neighbours; this ratio of modest address space against a moderate number of peers suggests a regional research and education backbone rather than a large-scale transit provider.

Notable

• Registrants align with the announcer, including South Dakota School of Mines & Technology, University of South Dakota, South Dakota State Government, and South Dakota Board of Regents.
• The inventory consists of four distinct IPv4 blocks and one IPv6 /32, reflecting a segmented estate supporting multiple state institutions and government entities.
