About this network

What it's used for

• The address space carries managed security infrastructure, evidenced by netnames OCD-UK-MDT (Managed Detection and Threat) and OCD-UK-UK1.
• The AS announces 768 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.

Notable

• Registrants align with the announcer, listing Orange Cyberdefense UK Limited and Abuse Contact for the primary prefixes.
• Orange Cyberdefense UK Limited is the result of Orange Group's 2019 acquisition of SecureData and SecureLink, which were subsequently rebranded into the unified Orange Cyberdefense division.
• The inventory is finely subdivided into three /24 blocks, consistent with internal segmentation for a corporate security provider.
