About this network

KEEN-AS is operated by KeenSystems B.V.

What it's used for

• The address space carries white-label telecommunications services, with netnames consistently formatted as NL-KEENSYSTEMS-YYYYMMDD and registrants listed as KS ADMINS; KeenSystems B.V.; KeenSystems NOC.
• The AS announces 4,864 IPv4 addresses across 7 prefixes and 2 IPv6 prefixes, while maintaining 121 observed neighbours; this ratio of moderate address inventory against a high neighbour count indicates a transit or network service provider role rather than a direct access network.
• Traffic from this AS consists of wholesale communications services, including VoIP, data, and connectivity infrastructure provided to other telecom operators and businesses under a white-label model.

Notable

• All registrants for the announced prefixes agree with the announcer, consistently identifying KeenSystems B.V. and its NOC.
• KeenSystems has operated as an independent white-label telecom provider since 2004, serving the Netherlands with communication services for other operators.
• The address inventory is subdivided into seven distinct IPv4 blocks, including a /24 and multiple /22 and /23 prefixes, reflecting a segmented corporate estate for different service segments or acquisition periods.
