This section lets you define the IP addresses that are allowed to connect to the preview endpoint. If no IP addresses are specified any IP address will be allowed. Allowed IP addresses can be specified as either a single IP address (e.g. ‘10.0.0.1'), an IP range using an IP address and a CIDR subnet mask (e.g. ‘10.0.0.1/22'), or an IP range using an IP address and a dotted decimal subnet mask   (e.g. ‘10.0.0.1(255.255.252.0)').
