About this network

MASTER-7-AS is operated by Mastercard Technologies LLC.

What it's used for

• The address space carries corporate infrastructure for a global payments company, evidenced by netnames such as MASTERCARD, MASTERCARD-AU, and MASTERCARD-IN.
• The AS announces 15,104 IPv4 addresses across 25 prefixes and 2 IPv6 prefixes, while maintaining 20 observed neighbours. This ratio of moderate address inventory to a limited peer set indicates an internal corporate estate rather than a transit or access network.

Notable

• Registrants are consistent with the announcer, primarily listing MasterCard Technologies LLC, with some prefixes registered to MasterCard AsiaPacific Australia Pty Ltd.
• The address inventory includes blocks with ATT netnames, such as 12.22.152.0/21 and 12.10.32.0/23, which are registered to AT&T Enterprises, LLC, suggesting historical leasing or acquisition of address space.
• The inventory is finely subdivided into /21, /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a large multinational corporation.
