How many IP's can a group have?

Hello

I found a list of countries IP ranges (http://www.ipdeny.com/ipblocks/) and created a deny firewall group so that anyone accessing my IP from say China, or Russia is dropped.

How large can the IP list be? There are over 100k lines of IP's listed through that website. 

If I add that to the config file, is it going to crash the EdgeMax?

Attached is a file of most IP ranges.
