About this network
ZAYO-CUSTOMER-17025 is operated by Zayo Bandwidth.
What it's used for
- The address space carries a mix of enterprise and educational traffic, evidenced by registrants such as Northwest Nazarene University (netnames NNU-2, NNU-199-104), BAE Systems Inc. (BAE-SYSTEMS-INC), and Siemens Industry Inc., Building Technology Division (ABOV-Z00020-64-124-134-0-24).
- With 14,592 IPv4 addresses announced across 42 prefixes and only 6 observed neighbours, the ratio suggests a transit or aggregation role rather than a large-scale access network, consistent with Zayo's infrastructure provider status.
Notable
- Registrants vary significantly from the announcer, including Northwest Nazarene University, BAE Systems Inc., Lansing Technology, Escalate, Siemens Industry Inc., TERRASPRING, and Latisys-Denver, LLC, indicating the AS aggregates space for multiple distinct customers.
- Zayo Bandwidth is the current holder, having acquired the assets of Level 3 Communications, which previously operated this AS number.
- The inventory includes two IPv6 prefixes (2001:438:38::/48, 2001:438:8022::/48) alongside a fragmented IPv4 estate with many /24 blocks.
