Summary
University of South Carolina
education university research legacy
The campus network of the University of South Carolina in Columbia.
What it's used for
- Campus networking for teaching, research and student access across the university system.
Notable
- Nine of the ten announced prefixes are slices of
129.252.0.0/16, all registered asSCAROLINA. The university holds one legacy class B and announces it in pieces rather than as a single route, which is usually done to steer traffic between upstreams or to keep parts of the campus reachable through different paths. - Five observed BGP neighbours for 67,000 addresses — an end site consuming connectivity.
- No IPv6 announced.
Interesting
- The tenth prefix breaks the pattern.
65.122.168.0/21is registered to CenturyLink under the netnameCENTURYLINK-LEGACY-QWEST-65-112-0, meaning it is provider space assigned from a carrier block that traces back to Qwest, which CenturyLink absorbed in 2011. The university announces it itself, so it is address space borrowed from an upstream rather than held outright — and the netname still carries the name of a company that has since been renamed twice over.

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 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
