AS15172 REINHARDT-WAL-1 - Reinhardt University
Unclassified ARIN
Summary
Reinhardt University
education business
One block, two upstreams, and a handle carrying a code that nothing else explains.
What it's used for
- A small university's network. A single IPv4
/24announced from the United States, no IPv6, and two observed BGP neighbours.
Notable
- The AS handle appends a three-letter code and a counter to the university's name, and neither the code nor the counter appears in any other field of the record.
- The netname is the university's name with a type word attached, and the registrant is the full institution.
- Three addresses were queried for reverse DNS and none returned a name.
- Two hundred and fifty-six addresses is the entire announced footprint.
Interesting
- A single
/24behind two upstreams is a university running its own AS number purely for redundancy. The addresses are portable, so either upstream can be dropped without renumbering, and that portability is the only thing the AS number buys at this size. - The unexplained code in the handle is the most common defect in this range. Handles are registered once, at a moment when the code meant something to whoever typed it, and then outlive that meaning entirely. There is no field where the expansion would be recorded even if someone remembered it.
- Nothing answering in reverse across a campus block means students and staff reach the internet through addresses that identify only the institution, not the building or the service.

Peering at a glance
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 2026-11-06, 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.
