For GKE nodes that must support a minimum of 60 and a maximum of 100 Pods per node, which per-node Pod CIDR size should you assign?

A /24 CIDR block provides 256 IP addresses. In GKE, some IPs are reserved for internal use (e.g., gateway, broadcast), leaving 254 usable IPs. This range comfortably accommodates the requirement for up to 100 Pods per node, as 100 is less than 254. A /25 CIDR provides 128 IP addresses, which is too small because it would only allow for 126 usable IPs (128 - 2 reserved), falling short of the 100 Pods requirement if some IPs are needed for other services or if the maximum is strictly 100 and not "up to". A /26 CIDR provides 64 IP addresses, which is insufficient for 100 Pods. A /28 CIDR provides 16 IP addresses, which is far too small.
