About this network

The AS handle INFOCO-COLRUYT-AS is held by Colruyt Group NV, a major Belgian retail corporation.

What it's used for

• The address space carries internal corporate infrastructure, evidenced by netnames such as BE-COLRUYT and COLRUYTNETWORK registered to the Colruyt Group Network Team.
• With 2304 IPv4 addresses announced across 4 prefixes and 95 observed neighbours, the ratio suggests a large-scale enterprise network with significant peering relationships rather than a transit provider.

Notable

• All registrants align with the announcer, consistently listing Colruyt Group NV and its network teams.
• The address inventory is finely subdivided into four distinct IPv4 prefixes and one IPv6 prefix, consistent with site-by-site segmentation for a large corporate estate.
