Autonomous system
AS13522 PUC PR CAMPUS CURITIBA
Unclassified RIPE
Summary
PUC PR Campus Curitiba
education research infrastructure
A university campus with seven upstreams and a netname that is the number 4456.
What it's used for
- A university campus network. 4,096 addresses in one IPv4 prefix,
200.192.112.0/20, seven observed BGP neighbours, and no IPv6 announced.
Notable
- The block is netname
4456, digits with no letters at all. - The AS handle recorded in inventory is the institution and campus name rather than a short code.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Seven neighbours is unusual for a single campus and says this network is a junction rather than an endpoint. Universities in a national research network peer with each other and with commercial providers, so a campus can end up carrying more relationships than its size suggests.
- A netname of digits alone identifies the registry that generated the record rather than the organisation holding it. Several networks in this range share the style, all from the same regional registry, all equally uninformative to anyone reading them.
- Naming the autonomous system after a specific campus rather than the university implies the other campuses have their own. Splitting by site is how a multi-campus institution keeps each one's connectivity independent of the others.

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.
