About this network

The AS handle KIRZ-AS-TH is held by KIRZ Company Limited.

What it's used for

• The address space is predominantly registered to KIRZ Company Limited under netnames such as KIRZ-AS-AP and KIRZ, indicating a dedicated service provider estate.
• With 23,552 IPv4 addresses announced across 17 prefixes and only 8 observed neighbours, the high address-to-neighbour ratio suggests an access or eyeball network rather than a transit provider.

Notable

• Most registrants align with the announcer, specifically KIRZ Company Limited, though two prefixes are registered to other entities: 80.174.160.0/22 to AIRE NETWORKS DEL MEDITERRANEO SL UNIPERSONAL and 38.225.104.0/23 to Cogent Communications, LLC.
• The inventory includes a single IPv6 prefix, 2407:7a00::/32, alongside the IPv4 blocks.
• The address inventory is finely subdivided into multiple /20, /21, /22, /23, and /24 prefixes, consistent with a corporate or ISP estate managing distinct customer or site segments.
