About this network

HM-AS is operated by H & M Hennes & Mauritz GBC AB.

What it's used for

• The address space carries corporate infrastructure for the Swedish fashion retailer, evidenced by netnames such as SE-HM, SE-HM-20160111, and HM-US.
• The AS announces 2064 IPv4 addresses across 8 prefixes with 4 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access network.

Notable

• Registrants for the majority of prefixes align with the announcer, listing Hennes Mauritz AB and H & M Hennes & Mauritz GBC AB.
• The inventory includes a small /28 block (116.51.16.112/28) registered to IRT-NTT-SG with netname NTT-GIN, which does not fit the primary H&M ownership pattern.
• The address inventory is finely subdivided into eight distinct prefixes, reflecting site-by-site segmentation typical of a large multinational corporation.
