APNIC doesn't give CIDR format? doh

So I've been busily firewalling off entire networks found to be remotely probing RDP, SSH, Radmin, SQL, etc that I see appearing in the logs, mainly just to drop them so I can see other more important things that may be blocked in the logs.
Unfortunately some of the big global registries don't report ranges in CIDR format.
Whois Search: 188.8.131.52
The range is "184.108.40.206 - 220.127.116.11"
What CIDR is that, and how do I figure that out?
Is there an easy calculator somewhere where I can just drop in the start and end addresses, and it spits out the netmask?

Country IP Blocks is what I use with pfBlocker:
IP Address assigned to: CHINA
IP Address: 18.104.22.168 is located within the following Network:
Network Range: 22.214.171.124 - 126.96.36.199
Total addresses: 4,194,304
You can enter an IP range into the alias field for a network alias and it will calculate the appropriate CIDR format address.
