Unassigns secondary private IPv4 addresses from a private NAT gateway. You cannot unassign your primary private IP. For more information, see Edit secondary IP address associations in the Amazon VPC User Guide.
While unassigning is in progress, you cannot assign/unassign additional IP addresses while the connections are being drained. You are, however, allowed to delete the NAT gateway.
A private IP address will only be released at the end of MaxDrainDurationSeconds. The private IP addresses stay associated and support the existing connections, but do not support any new connections (new connections are distributed across the remaining assigned private IP address). After the existing connections drain out, the private IP addresses are released.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginUnassignPrivateNatGatewayAddress and EndUnassignPrivateNatGatewayAddress.
