Summary

Oracle Corporation

United States of America · AI-generated

cloud enterprise business

ORCL-CHICAGO-PP is operated by Oracle Corporation.

What it's used for

  • The address space carries Oracle Public Cloud infrastructure, evidenced by netnames such as OC-195 and ORACLE-4, alongside legacy blocks registered to Oracle Svenska AB.
  • With 304,640 IPv4 addresses and 614 IPv6 prefixes announced against 33 observed neighbours, the high address-to-neighbour ratio indicates a large-scale cloud and enterprise service provider rather than a transit carrier.
  • Traffic from this AS consists of cloud computing workloads, database services, and enterprise application endpoints hosted on Oracle's global infrastructure.

Notable

  • Registrants align with the announcer, including Oracle Public Cloud for the largest /20 blocks and Oracle Corporation for /21 blocks.
  • The inventory includes blocks registered to Oracle Svenska AB, reflecting Oracle's historical presence in Sweden prior to consolidation under the main US entity.
  • The address inventory is finely subdivided into 237 IPv4 prefixes, consistent with an internal corporate estate segmented by service or region.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
