AS14529 SJU-5600
Unclassified ARIN
Summary
Saint Joseph's University
education research infrastructure
A single block announced whole, and an AS handle carrying four digits that appear nowhere in the addresses.
What it's used for
- A university's campus network. 65,536 addresses in a single IPv4 prefix,
129.68.0.0/16, with three observed BGP neighbours and no IPv6 announced.
Notable
- The block carries the netname
SJU-NET, registered toSaint Joseph's University. - The AS handle is
SJU-5600. - Three addresses were queried for reverse DNS and none returned a name.
Interesting
- The number in the handle is not part of the address space, not the AS number and not the block size. Handles are free text, and organisations reach for whatever number already identifies them internally, which is usually a street address or a department code. It means something to the person who filed it and nothing to anyone else.
- The whole range is announced as one prefix. A campus network that never had to split its announcement is one whose growth all happened behind the same door.
- Three neighbours for a single-campus university is more than the minimum. Research and teaching traffic tend to arrive over different arrangements, and a regional education network often sits alongside the commercial providers.
- The netname says
NETafter the initials, a habit from when a registry record described a network rather than an owner. Nothing else in the entry adds detail, and nothing answers a reverse lookup either.

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 2026-10-24, 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 2026-10-24. 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.
