AS11546 UNOMAHA-AS

UNOMAHA-AS is held by the Board of Regents of the University of Nebraska and is associated with the University of Nebraska at Omaha. RIS sees a single IPv4 prefix, 129.93.50.0/23 — about 512 addresses — no IPv6, and a single observed BGP neighbour.

What it's used for

Campus connectivity, but only a slice of it. The /23 is registered to the Board of Regents under the netblock handle HUSKERNET, the university system's own network, and 129.93.0.0/16 is the classic University of Nebraska block. What this AS announces is one /23 carved out of that space, with exactly one upstream. That shape — tiny prefix, single neighbour, parent block held by the same organisation — is what you see when a university spins up a separate AS number for a specific piece of the estate rather than for the campus as a whole: a service that needs its own routing policy or its own upstream, announced independently of the main university AS.

Notable

Do not read the 512 addresses as the size of the university's network. The University of Nebraska's routable estate is far larger; it is simply announced from elsewhere. The address count here measures what this AS number carries, not what the institution owns — a distinction that matters constantly in a range full of institutional ASNs.

Interesting

One neighbour means no redundancy at the BGP layer for this particular announcement, which is a further hint that it is a purpose-specific attachment rather than the university's production front door.
