Education ARIN
Summary
Milwaukee School of Engineering
education university legacy
MSOE-INTERNET is the campus network of the Milwaukee School of Engineering (MSOE), a private university in Milwaukee, Wisconsin specialising in engineering, computing, nursing and business. Everything the AS carries is university space: all eight prefixes RIS sees are registered to the MSOE org, Milwaukee School of Engineering.
What it's used for
Campus connectivity for a single institution. The AS announces 8 IPv4 prefixes totalling 65,536 addresses, and no IPv6 at all. The address total is exactly one legacy Class B, and the prefix list bears that out: a covering 155.92.0.0/16 plus a set of more-specifics carved out of it (/18, /19, /20, and a few /24s). That is one block being announced at several granularities, not an accumulated inventory. The more-specifics are the ordinary result of splitting a campus block across upstreams or steering traffic for particular subnets, not separate acquisitions.
Notable
Only 2 observed BGP neighbours. That is the decisive role signal here: it says MSOE buys transit and does not sell it. Read against the address count, this is the classic university shape, a substantial block of end-user space (dorms, labs, faculty and staff) reached through a couple of upstreams, with no peering fabric behind it. Nothing about the routing suggests hosting, transit or any commercial service.
Interesting
Every prefix is self-registered and every prefix is a more-specific of the same /16, so there is nothing to reconcile between who holds the AS and who holds the space. Cards in this range often need that check; this one clears on the first pass.

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 2026-11-08, 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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
