Summary
Netnt Sistemas e Informatica
isp brazil small
AS52731 is operated by Netnt Sistemas e Informatica Ltda.
What it's used for
- The address space is registered under the netname
517212for both announced IPv4 prefixes. - The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small access or local network rather than a transit provider.
- Traffic from this AS consists of local subscriber or business endpoints in the Rio de Janeiro region, specifically associated with the cities of São João da Barra and Cardoso Moreira.
Notable
- Registrants for both IPv4 prefixes match the AS holder, Netnt Sistemas e Informatica Ltda.
- The address inventory is small and concentrated in the 177.84.248.0/23 and 177.84.250.0/24 blocks, consistent with a regional ISP footprint.

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: 454 networks and 1,854 prefixes, as published 2026-11-09. 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.
