AS11659 KUMC

KUMC is the autonomous system of the University of Kansas Medical Center, the academic health campus of the University of Kansas in Kansas City, Kansas, home to its schools of medicine, nursing and health professions and their affiliated research and clinical operations.

What it's used for

Campus connectivity for a single academic institution. RIS sees eight announced v4 prefixes carrying 65,536 addresses — the whole of 169.147.0.0/16, a legacy class B — against four observed neighbours. That combination is the signature of a self-hosting campus network rather than a provider: a provider with a /16 of space would peer with far more than four ASes, while a university announcing exactly its own historical block through a small set of upstreams and regional research links is the ordinary picture.

Notable

Every prefix in the RIS window sits inside 169.147.0.0/16, and ARIN registers each of them to the University of Kansas Medical Center under the UKANSMC handle. Holder and registrant are the same organisation with no third parties in between, so nothing here suggests leased or brokered address space.

Interesting

The more-specific announcements — a /17, two /20s, a /22 and several /24s all carved out of the same /16 — are classic inbound traffic engineering: the covering block is announced everywhere while individual chunks are steered towards particular upstreams, a normal way for a multihomed campus to balance load and keep clinical traffic on a preferred path.
