Summary
Universidade Federal de Santa Catarina
education university research legacy
AS11242 belongs to the Universidade Federal de Santa Catarina (UFSC), the federal university in Florianópolis, Brazil. UFSC is not only a campus: it hosts PoP-SC, the Santa Catarina point of presence of RNP, Brazil's national research and education network.
What it's used for
Academic networking for the university and the state's research community. RIS observes two IPv4 prefixes — 200.237.192.0/18 and a /20 more-specific inside it, roughly 16,384 addresses — three IPv6 prefixes under 2801:80:a80::/44, and 21 observed neighbours.
Those 21 neighbours are the detail worth dwelling on. A campus network of this size would normally show two or three; 21 is what a network gets from sitting on an internet exchange. This is consistent with UFSC's PoP-SC role: a regional academic PoP peers at the local IX.br exchange with commercial ISPs and content networks in addition to carrying RNP transit, so its neighbour count looks far more like a small regional carrier's than a single university's.
Notable
The one sampled PTR reinforces the PoP reading rather than the campus one: remep-edd-cpe-unisul-braco-do-norte.remep.pop-sc.rnp.br is a customer-premises router of REMEP, the metropolitan research network, serving a different institution (UNISUL) in a different town. The AS therefore carries space delegated onward to other Santa Catarina academic sites, not just UFSC's own campus.
Interesting
RDAP lookups for both prefixes failed when the evidence was gathered, so the registrant could not be confirmed from the registry — an absence of data, not a finding.

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: 436 networks and 1,771 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.
