Q:

Remote Mysql Database Access error when adding wildcard IP like 192.168.1.%

I am trying to whitelist my IP address in MySQL database remote connection in cPanel
Remote Mysql Database Access gives error when I try to add an IP with wildcard like 192.168.1.%
Error: Error: 182.64.171.% is not a valid remote host
All other exact IP like: 123.123.123.123 do not give error. 
I want to add wildcard for last 2 range.  Like 182.64.%.% because my ISP changes last 2 range. 
Please see:

A:

Try removing the wildcard and adding a subnet description like:
182.64.171.0/255.255.255.0

This will allow access from the whole class C subnet.
