Unclassified APNIC
Summary
South Dakota Research and Education Network
education government research state
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), andNET-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.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
