About this network

ONECOM is operated by One.com A/S, a Danish web hosting and domain registration provider.

What it's used for

• The address space carries infrastructure for web hosting and domain services, evidenced by netnames such as DK-ONECOM-20100908 and ONECOM-INFRA, and reverse DNS entries pointing to pub.network.g1i.one.
• With 26,880 IPv4 addresses announced across 15 prefixes and 177 observed neighbours, the high neighbour-to-address ratio indicates a transit-heavy role, consistent with a hosting provider connecting to multiple upstreams and peers.
• Traffic from this AS consists primarily of web hosting endpoints, domain name system services, and associated API traffic for One.com’s customer base.

Notable

• Registrants are mixed: most prefixes are registered to One.com RIPE Administrators or One.com A/S, but several blocks including 91.184.0.0/19 and 185.95.24.0/22 are registered to Hostnet Network Operations and Hostnet B.V., indicating leased or acquired space from a separate entity.
• The inventory includes prefixes registered to GROUP.ONE NORWAY AS, reflecting One.com’s Nordic expansion and corporate structure.
• The address inventory is fragmented across multiple /22 and /21 blocks, with a single large /19 block, suggesting organic growth through multiple acquisitions or allocations over time.
