About this network

SUBRIGO is operated by Subrigo Corporation.

What it's used for

• The address space carries static IP assignments for communications and data center services, evidenced by reverse DNS entries such as static-0.82.229.138.ops.subrigo.net and 0.mail.carrierops.com.
• With 18,432 IPv4 addresses announced across 34 prefixes and 24 observed neighbours, the ratio suggests a regional access and hosting provider rather than a large-scale transit backbone.

Notable

• Registrants are predominantly consistent with the announcer, listing SUBRIGO CORPORATION for most blocks, though one prefix (65.171.146.0/23) is registered to APOGEE dba PAVENET and another (104.255.150.0/23) to SUBRIGO NETWORKS CORPORATION.
• The inventory is finely subdivided into numerous /22 and /23 blocks, indicating site-by-site segmentation typical of a corporate estate or multi-location ISP.
