About this network

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.
