About this network

What it's used for

• The address space carries corporate infrastructure, evidenced by netnames UK-CYLOLTD-20080411 and UK-CYLOLTD-20260630 registered to NOC; Cylo Ltd; Abuse-C Role.
• The network announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 115 observed neighbours; this ratio of small address inventory to high peering count indicates a transit or interconnection role rather than a large access network.
• Traffic from this AS consists of web and API endpoints for a media technology company that helps clients create customer engagement and retention solutions.

Notable

• Registrants for both announced prefixes agree with the announcer, listing NOC; Cylo Ltd; Abuse-C Role for both 79.140.195.0/24 and 85.8.234.0/24.
• The address inventory is small and finely subdivided into two /24 blocks, consistent with an internal corporate estate rather than a broad consumer base.
