How to ban 250.000 IP ranges?

How to ban 250.000 IP ranges?

I am using iblocklist.com and I want to ban a list of IPs I made from
accessing my web server on a CentOS dedi.
I have a bash script that can parse it and add the ranges one by one to
iptables. My issues are:
It takes way too long. Anyway to speed up the processes?
Will iptables even be able to handle this kind of load?
Thanks
