Unclassified APNIC
Summary
Universidad Nacional del Sur
education research infrastructure
Both of its netnames are written as ranges with a dash, and one of them describes a block sixteen times larger than what is announced.
What it's used for
- A university's network. 6,144 addresses across two IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Interesting
- Writing a netname as a first and last address separated by a dash is a registry convention that predates the notation everyone now uses, where a block is a starting address and a length. The older form survives here in a record that has never needed rewriting.
- The second netname covers a far wider range than the university announces, because the block belongs to the national academic interconnection network and the university holds a slice of it. The registry names the pool; routing shows the portion.
- Three neighbours for a campus that announces both its own space and its slice of the academic network is the standard arrangement in a country where research traffic and commercial traffic take separate paths.
- Nothing answers a reverse lookup, which for a university is unusual enough to be a decision rather than neglect.

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 2026-10-20, 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 2026-10-21. 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.
