Summary

Brazil · AI-generated

automotive corporate brazil

AS28243 is operated by FCA Fiat Chrysler Automóveis Brasil Ltda.

What it's used for

  • The address space is registered under the netname 120531 and belongs to the automotive manufacturer FCA Fiat Chrysler Automóveis Brasil Ltda.
  • The AS announces a single IPv4 prefix, 187.0.248.0/21, comprising 2048 addresses, with no IPv6 prefixes in inventory.
  • With only 2 observed neighbours, the low neighbour count relative to the address block suggests an internal corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant matches the AS holder exactly, confirming direct ownership of the announced space.
  • The inventory consists of a single contiguous /21 block, indicating a finely subdivided internal network typical of a large corporate site.

Reputation

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 1,771 prefixes, as published 2026-10-15. 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.
