Summary
University of Alabama
education university legacy
The campus network of the University of Alabama in Tuscaloosa.
What it's used for
- Campus networking for teaching, research and student access.
Notable
- One prefix, one netname, one registrant:
130.160.0.0/16asUANET. Exactly 65,536 addresses announced as a single route, with no deaggregation at all. - Three observed BGP neighbours. An end site reached through a small number of upstreams, most likely including the state research network.
- No IPv6 announced.
Interesting
- This is the cleanest possible shape for a university AS. A legacy class B handed out before address scarcity, still announced whole decades later, with nothing bolted on and nothing borrowed from a provider.

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 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
