About this network
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.
