What it's used for
- The address space carries fiber-to-the-home (FTTH) and dedicated services, evidenced by reverse DNS entries such as
ftth.aux.toledofibra.net.branddedicado.toledofibra.net.br. - The AS announces 3,328 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 31 observed neighbours; this ratio indicates a regional access network rather than a transit provider.
- Traffic consists of residential and business internet subscribers in the Tocantins region of Brazil, utilizing the operator's fiber infrastructure for broadband connectivity.
Notable
- All RDAP registrants for the announced prefixes match the AS holder,
TOLEDO FIBRA TELECOMUNICAÇAO LTDA, confirming consistent ownership of the address space. - The inventory includes a distinct /24 prefix (
143.208.7.0/24) with reverse DNS pointing todedicado.tocantins.net.br, suggesting a separate or legacy segment within the corporate estate.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
