it helps some times You cannot express exclusions with CIDR notation. You can give up bunch of IP addresses by using /25 range.

Speeding up checking of IP address membership in CIDR ranges, for large datasets

To fix the issue you can do In a Postgres DB, I need to filter a set of several hundred thousand rows in a table A by including only those rows for which an IP address column (of type inet) in the row matches any of several thousand IP address blocks (of type cidr) in another table B. I've tried various indexes on the inet addresses in the first table and the cidr ranges in the second, but no matter what I do, the planner does a nested sequential scan, applying the << operator to every pair of IP addresses and prefixes. , Case closed. To make things fast, do the following:

What is the best and quickest way to block / allow only ranges IPS by CIDR (lock / permission ranges IPs of a country)

may help you . Using the Allow and Deny is probably faster because it doesn't require running a script. The htaccess file will need to be read but as long as it's unchanged, nothing else needs to happen. It would work even faster if you put them in the server/vhost config instead of an htaccess file.
As for allocation blocks, there's several places that you can google:

help you fix your problem Just loop through the list of ranges, and use array_merge() to append the results to the collection of all results.
code :
$ranges = [
    ["start" => "8.8.8.0", "end" => "8.8.8.16"],
    ["start" => "192.168.10.5", "end" => "192.168.32.255"],
    ["start" => "10.1.2.32", "end" => "10.1.3.0"]
];
$allCidrs = [];
foreach ($ranges as $range) {
    $cidr = iprange2cidr($range["start"], $range["end"]);
    $allCidrs = array_merge($allCidrs, $cidr);
}

How to provide for 2 different IP ranges? --pod-network-cidr= for multiple IP ranges

will be helpful for those in need --pod-network-cidr is for IPs of the pods that kubernetes will manage. It is not related with nodes of the cluster.
For nodes, the requirement is (from Kubernetes doc):

To fix the issue you can do You can use ipcalc to calculate cidr from IP range :
