Summary
St. Catherine University
education research infrastructure
Two /19s from one range with a quarter of it missing in between, and a /24 whose netname bothers to say it is IPv4.
What it's used for
- A university campus network. 16,640 addresses across three IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.
Notable
140.225.0.0/19and140.225.128.0/19both carry the netnameSTKATE-NET, registered toSt. Catherine University.- The third block is
23.138.116.0/24, netnameSTKATE-IPV4-24. - Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- The two
/19s are not adjacent. They sit at the start and the midpoint of the same range, which means the space between them is either used without being announced or belongs to somebody else entirely. A shared allocation split between institutions leaves exactly this fingerprint. - Writing
IPV4into a netname is only worth doing once both protocols exist and the distinction can be ambiguous. The two older blocks predate the question and say nothing about it, so the netnames date themselves. - That third block also comes from a range issued long after the first two, in
/24units, which is what an institution buys or is allocated once the easy space is gone. Two/19s from the old world and one/24from the new. - Three neighbours on three prefixes is better redundancy than most campuses in this range manage, and announcing no IPv6 at all is the more surprising half of the record.

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 2026-10-21, 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 1,779 prefixes, as published 2026-10-22. 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.
