Unclassified LACNIC
Summary
NTT do Brasil
telecom transit isp
Twenty-five neighbours behind a single /19, and the netname is the number 781.
What it's used for
- A telecommunications carrier's network. 8,192 addresses in one IPv4 prefix,
200.194.64.0/19, twenty-five observed BGP neighbours, and no IPv6 announced.
Notable
- The block is netname
781, digits with no letters at all. - The AS handle recorded in inventory is the company's full legal name including its legal form.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Twenty-five neighbours against one /19 is the signature of transit rather than hosting. The addresses are the smaller half of what this network does; carrying other people's traffic is the larger half, and that leaves no trace in an address count.
- A netname of digits alone comes from a registry generating records from a database, where the number is a row identifier. Several networks in this range carry the same style, so the naming says which registry created the object rather than anything about the network.
- A global carrier's local subsidiary announcing one block is what a country operation looks like from outside: the parent's name in the registry, a single range of local address space, and the peering that makes it worth being there.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
