Summary
Alfred University
education research infrastructure
A small university holding a whole /16, announced as one route with nothing underneath it.
What it's used for
- A university's network. 65,792 addresses across two IPv4 prefixes,
149.84.0.0/16and192.31.254.0/24, four observed BGP neighbours, and no IPv6 announced.
Notable
- Both blocks are netname
ALFRED, registered to the university. - The /16 is announced whole rather than split into pieces.
- Six addresses were queried for reverse DNS and none returned a name.
Interesting
- Sixty-five thousand addresses for an institution of a few thousand people is the arithmetic of early allocation. Universities asked, and the answer was a /16, because the pool looked infinite and the paperwork for anything smaller was the same paperwork.
- Announcing it as a single route is the opposite of what most large holders in this range do. It keeps one entry in every router on the internet instead of a dozen, and it works because a campus with four upstreams has nothing to steer between them.
- The extra /24 is from a range handed out in the same era for organisations that needed a second small block. Holding both, decades later, with the same netname on each, is a network nobody has had a reason to reorganise.

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 2026-10-22, 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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
