About this network

GASUNIE is the autonomous system for N.V. Nederlandse Gasunie.

What it's used for

• The address space carries corporate infrastructure for a Dutch natural gas company, with netnames explicitly set to GASUNIE for both announced IPv4 blocks.
• The AS announces 2560 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
• Traffic from this AS consists of internal corporate communications, operational technology, and administrative endpoints for the gas infrastructure operator.

Notable

• Registrants for both the 31.132.200.0/21 and 91.229.152.0/23 prefixes are listed as N.V. Nederlandse Gasunie, fully aligning with the AS holder.
• The address inventory is compact and finely subdivided, consistent with an internal corporate estate segmented by site or function rather than a public-facing service.
