Summary
Carlow University
education university legacy
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.

Interconnection
Peering at a glance
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 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
