Unclassified ARIN
Summary
University of the Free State
education university south-africa
The AS handle UOFS is held by University of the Free State.
What it's used for
- The address space carries the network infrastructure for a multi-campus public university in Bloemfontein, South Africa.
- The AS announces 198656 IPv4 addresses across 6 prefixes and 2 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio indicative of an isolated educational network rather than a transit provider.
Notable
- All RDAP registrant lookups for the announced prefixes returned UNAVAILABLE, so registrant agreement with the announcer could not be verified.
- The address inventory is dominated by the large 196.254.0.0/15 block, supplemented by smaller allocations in the 196.21.0.0/16 and 146.182.0.0/16 ranges.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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 1,778 prefixes, as published 2026-10-20. 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.
