What it's used for

  • The address space is registered under netnames 424489, 424483, 424484, 131812, and 424479, all attributed to the Rio de Janeiro state government's information technology center.
  • The AS announces 19456 IPv4 addresses across 12 prefixes and maintains 8 observed neighbours, indicating a role as a government enterprise network rather than a transit provider.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
