Summary
University of Memphis
education research infrastructure
Every block is filed under five letters that are not an abbreviation of the university's current name.
What it's used for
- A university's campus network. 65,536 addresses across nine IPv4 prefixes, with seven observed BGP neighbours and no IPv6 announced.
Notable
- Every record checked carries the netname
MEMST, registered toThe University of Memphiswith an IT infrastructure team as contact. - The nine prefixes tile
141.225exactly: a/17,/18,/19,/20and/21halving down the range, then a/22, a/23and two/24s covering the last stretch. - Eighteen addresses were queried for reverse DNS and none returned a name.
- The registry lookup for
141.225.128.0/18failed.
Interesting
MEMSTis what the institution was called when the block was registered. Renaming a university updates the letterhead and the domain long before it reaches a registry record that nothing depends on, so the old name survives in the one field nobody thinks to change.- The split starts as a textbook halving chain and then loses patience: the last eighth is cut into a
/22, a/23and two separate/24s. That is a range subdivided on paper at the start and then carved up as needs arrived. - Seven neighbours is high for a single campus. Universities sit on research networks, regional education networks and commercial transit at once, and every one of those arrangements counts.
- Nothing answers a reverse lookup anywhere in it.

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 2026-10-14, 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 1,773 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.
