Summary
Missouri University of Science and Technology
education university research legacy
MST is the Missouri University of Science and Technology in Rolla — the University of Missouri System's engineering and science campus, formerly the University of Missouri–Rolla. The AS announces the campus network.
What it's used for
Campus connectivity: student residences, faculty and staff, labs and departmental servers. RIS sees 3 v4 prefixes / 66,048 addresses, no IPv6 in the observed window, and 2 observed neighbours. The shape is a textbook university: a large flat address holding served by a very small number of upstreams, almost certainly a state research-and-education network plus a commercial backup, rather than the hundreds of adjacencies a transit carrier shows. Nothing routes through this AS; it exists so the campus can multi-home its own space.
Notable
Almost the entire address count is one prefix — 131.151.0.0/16, registered as MST-CAMPUS — the historic class-B allocation that essentially is the campus. Two additional /24s, 192.65.97.0/24 (MST-EEC) and 192.55.114.0/24 (MST-EXTERNAL), are also registered directly to the university. Every prefix registers to the holder itself, with no third-party registrants anywhere in the inventory, which is what you expect from an institution that has held its own space since well before address scarcity.
Interesting
The netnames are internal department codes rather than marketing: MST-EEC most plausibly tracks an engineering unit, and MST-EXTERNAL a block used for externally reachable services. The absence of any announced IPv6 in the RIS window is notable for a large technical university, where v6 on campus is otherwise common.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
2 upstream, 0 downstream and 2 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,782 prefixes, as published 2026-10-16. 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.
