What is an Assignment Window (AW)?
An Assignment Window (AW) is the maximum amount of IP addresses that you, as a Local Internet Registry (LIR), can assign to End Users or to your own infrastructure from your allocations without prior approval from the RIPE NCC.
The AW for a new LIRs is 0 (zero). This means that every assignment made by the LIR requires prior approval by the RIPE NCC.
An AW enables an experienced Local Internet Registry (LIR) to evaluate address requests without having to interact with a RIPE NCC IP Resource Analyst (IPRA).
