Summary
Telium Telecomunicacoes Ltda (Telium Networks)
isp hosting legacy
AS11432 is Telium Telecomunicações Ltda, trading as Telium Networks: a Brazilian carrier and data-centre operator selling dedicated links, cloud and IP telephony to corporate customers.
What it's used for
RIS shows 104 announced IPv4 prefixes covering 43,776 addresses, plus 9 IPv6 prefixes under 2804:138::/32. The IPv4 space is almost entirely LACNIC 200.x legacy Brazilian allocations — 200.170.192.0/18, 200.155.128.0/18, 200.201.128.0/19 — announced both as aggregates and as a long tail of /22s. That deaggregation pattern is normal for a Brazilian operator distributing space across many points of presence and peering at IX.br.
The reverse DNS is the clearest signal of what the space carries. Most sampled addresses sit under static.telium.net.br, the operator's own zone, and the word static is the point: these are fixed addresses assigned to customers on dedicated circuits, not dynamic consumer pools. Two samples resolve into customer-owned domains instead — a commodity-trading firm and a hosting portal — which is exactly what corporate dedicated-access and colocation space looks like from the outside.
Notable
256 observed neighbours against a modest 43k addresses would normally suggest a wholesale carrier, but in Brazil it is also what dense IX.br participation produces: a mid-size ISP peering at multiple exchanges racks up hundreds of adjacencies without selling much transit. Read alongside the corporate rDNS, this is a business-access and data-centre network with heavy peering, not a pure transit backbone.
Interesting
One /24 in the pack is registered to Voices Telecomunicações rather than Telium, and one is Cogent provider-assigned space. Neither is a third-party leasing tell: carrier-assigned blocks and related-operator registrations are ordinary in Brazilian routing. Several registry lookups for the large aggregates failed outright, which is missing data, not a clearance.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
