What it's used for

• The address space carries corporate infrastructure, evidenced by netnames ORG-ISV3-RIPE and UIT-SRV1 registered to ISV Tech.
• The AS announces 1792 IPv4 addresses across 4 prefixes with only 1 observed neighbour, a ratio indicating an internal corporate estate rather than a transit or access network.

Notable

• Registrants for the majority of the space align with the announcer, specifically ISV Tech LIMITED, though one prefix (149.7.27.0/24) is registered to Cogent Communications, LLC.
• The address inventory is small and finely subdivided into four distinct blocks, consistent with site-by-site segmentation for a global technology company.
