Unclassified RIPE
Summary
Usmanu Danfodiyo University
education university nigerian public
The AS handle Usmanu is operated by Usmanu Danfodiyo University.
What it's used for
- The address space carries the university's internal network infrastructure, as indicated by the registrant name and the lack of commercial or residential reverse-DNS indicators.
- The AS announces 17,408 IPv4 addresses across 2 prefixes (82.101.128.0/18 and 41.78.224.0/22) with only 1 observed neighbour, a ratio that implies an isolated access or campus network rather than a transit provider.
Notable
- The registry holder and AS handle both identify the operator as Usmanu Danfodiyo University, confirming the identity of the announcer.
- The university was formerly known as the University of Sokoto before being renamed in honor of the scholar Usmanu Danfodiyo.
- The inventory consists of two distinct IPv4 blocks, one in the 82.101.0.0/16 range and one in the 41.78.0.0/16 range, with no IPv6 prefixes announced.

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 1,781 prefixes, as published 2026-10-16. 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.
