The RIR Registration tool registers information associated with a domain with its corresponding Regional Internet Registry(RIR). Registering subnets with an RIR assists in tracking IP addresses and how they are allocated to ensure proper distribution of IP addresses based on region. SoftLayer’s RIR Registration tool registers a specified Person Record for each subnet. Each Person Record associated with an account may be used for subnet registration and details for the Records may be updated at any time.
