About this network

STACKSINC-GLOBAL is operated by Stacks Inc, a small network and internet services company based in Denver, Colorado (stacksinc.net).

What it's used for

• Stacks Inc's PeeringDB record lists the network as a mix of Cable/DSL/ISP, enterprise, and network services with a global scope; the company markets high-speed internet and IPTV to home and business customers.
• AS5068 announces roughly 1,280 IPv4 addresses. The company also operates AS398704 (STACKSINC-BACKBONE).

Notable

• The low number is a reissue: ARIN registered AS5068 to Stacks Inc in 2024, and the organization record only dates to 2020. There is no early-internet lineage here.

Interesting

• Name trap: Stacks Inc is unrelated to STACK Infrastructure, the hyperscale data center operator, despite both being associated with Denver.
