Summary
Black Hills State University
education university sdnet us
The AS handle BHSU is operated by Black Hills State University.
What it's used for
- The address space carries university infrastructure, evidenced by netnames such as
DDN-BHSU-2,SDNET-BHSU-SDLN, andBLACKHILLS. - The network announces 2,304 IPv4 addresses across 8 prefixes while maintaining only 2 observed neighbours, a ratio indicative of a small, self-contained institutional network rather than a transit provider.
Notable
- All registrants in the RDAP data align with the announcer, consistently listing Black Hills State University for every prefix.
- The inventory consists of eight distinct IPv4 blocks, including a /23 and seven /24s, with no IPv6 prefixes currently announced.

Internet exchanges
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 2026-11-05, 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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
