What it's used for

• The address space carries hosting and colocation infrastructure, evidenced by netnames such as COLOEXCHANGE and SECURENET-IP4-US-6.
• With 14,592 IPv4 addresses announced across 13 prefixes and only 6 observed neighbours, the ratio suggests a hosting or business network rather than a transit provider.

Notable

• Registrants include IO INC, COLOEXCHANGE.COM A CALIFORNIA CORP, Spry Servers, LLC, OpenMobile Inc., and USASERVERSTORE INC., indicating a mix of owned and leased or partner space.
• The address inventory is finely subdivided into multiple /21, /22, /23, and /24 blocks, consistent with an internal corporate estate or multi-tenant hosting environment.
