Routing & resources
Address space
AS215248 originates its own IPv4 and IPv6 space as a RIPE LIR resource holder. Everything is dual-stack with IPv6 treated as a first-class citizen, not an afterthought.
IRR & filtering
Routes are documented under the AS-SET RIPE::AS215248:AS-BASTIAANBRINK. Peers are encouraged to build prefix filters from IRR data and to apply RPKI ROV.
RPKI
11 of 12 prefixes carry valid ROAs; 1 not yet covered. AS215248 also performs RPKI Route Origin Validation on received routes.
