AS11009 CARLOWUNIV

CARLOWUNIV is the autonomous system of Carlow University, a private Catholic university in the Oakland neighbourhood of Pittsburgh, Pennsylvania. ARIN records the holder at 3333 Fifth Avenue, Pittsburgh — the university's own campus address, not a proxy or an agent.

What it's used for

Campus connectivity, and only that. RIS sees a single announced IPv4 prefix, 198.206.255.0/24 (256 addresses), and no IPv6 at all. That /24 is registered to CARLOW-U in ARIN, so the university holds its own space rather than announcing an upstream's or a third party's — the plainest signal that this is a real end-site operator and not a number wearing someone else's inventory.

The routing shape matches an enterprise edge rather than a network that sells transit: two observed BGP neighbours. A wholesale carrier of any size peers with hundreds of ASes; a campus that runs BGP purely to multihome its own /24 for redundancy peers with the two providers it buys from. Everything behind it is university-operated: staff and faculty desktops, student services, whatever public-facing hosts the institution runs itself.

Notable

The scale is worth stating plainly. A single /24 is a small footprint for a university, which suggests most of the campus sits behind NAT or on provider-assigned space, with this block reserved for the servers and services that need stable, university-owned addressing.
